Bloom · Lemmy

Lemmy posts, measured rather than assumed.

Bloom schedules and publishes to Lemmy as title-first link-aggregator posts, accepts an image upload, and enforces a 5,000-character body limit.Lemmy is one of the ten Bloom networks that report engagement back, so community reach is a figure rather than a guess — but it returns no conversations, which means replies and comment threads stay on Lemmy itself rather than arriving in Bloom’s inbox. The account links with a pasted credential. Lemmy is one of the nine networks no mainstream scheduler supports, and one of eighteen Bloom publishes to in total.
A four-stage diagram of Bloom's fediverse coverage. Lemmy appears in the first stage, where all nine networks publish, and in the second, where five report engagement — but not in the third, where only Mastodon and Bluesky return conversations.
Lemmy clears two of the four stages: it publishes and it reports.
01 · On Lemmy specifically

Title-first posting, with a number attached.

A Lemmy post is not a status update. It is a submission to a community with a title doing most of the work, which is a different writing job from a microblog and a different scheduling job too — the title is the thing that gets read, and the body is what justifies the click. Bloom composes it that way rather than pushing a timeline post sideways into a link aggregator, and because Lemmy is one of the networks whose API reports back, what happened next is a measured figure instead of an impression formed by scrolling.

Image upload, stated because it is specific

Media upload is accepted by eight of Bloom’s eighteen networks, and Lemmy is one of them for images. That is worth naming because most link-aggregator integrations are text-and-URL only; an image submission behaves differently in a community feed, and the difference is visible in the engagement Bloom then reads back.

Reach you can compare across networks

Because Lemmy reports, its posts sit in the same analytics as Mastodon, Bluesky, Misskey and dev.to — five of the nine fediverse networks. The four that do not report are listed as not reporting rather than shown as zeros next to them, which is what stops a comparison being quietly wrong.

02 · 5,000 characters

Five thousand characters, and a title that matters more.

Lemmy sits at the top of Bloom’s limit range, level with Mbin, dev.to and Tumblr and sixteen times what Bluesky accepts. In practice the ceiling is rarely the binding constraint on a community submission — the title is. Bloom still enforces the 5,000 at compose time, because a body silently cut at the limit inside a community that values completeness is a worse outcome than being told to trim it yourself.

Native threads and carousels do not apply here: threads exist on three of the eighteen networks and carousels on two, and Lemmy is on neither list. Bloom declares both absences at compose time instead of accepting the shape and failing at the slot. The same preflight runs the character count, the media rule and the format rule together, which is why a Lemmy post either goes out as written or never gets stored. Every limit for all eighteen networks is tabulated on the coverage page.

03 · Linking the account

A pasted credential, one per instance.

Lemmy is one of the nine Bloom networks connected with a credential you paste rather than an OAuth redirect. Since Lemmy instances are independent, an account is added per instance, and each one becomes its own connected account inside the workspace — with its own throughput budget and its own place in the role model.

Per-account throughput, not per-platform

The rate governor sits in front of each connected account with a maxPerDay ceiling and a minIntervalMinutes gap. Two Lemmy accounts on two instances therefore never share one budget, which matters because community norms differ sharply from one instance to the next.

Encrypted at rest

Credentials are stored under AES-256-GCM with a scrypt-derived key. The connect method decides how a credential arrives; it has no effect on how it is kept afterwards.

Five roles, eight actions

Owner, admin, editor, client and viewer are checked against eight distinct actions. Submitting to a community and connecting the account that submits are separate permissions, which is what lets a client watch a Lemmy plan without holding its credential.

04 · What comes back

Engagement returns. Conversations do not.

Lemmy is on the useful side of one line and the honest side of another. It is one of ten Bloom networks that report engagement, so likes, comments and reach come back as data. It is not one of the seven that return conversations: Bloom registers no Lemmy inbox source, so comment threads are read on Lemmy rather than in Bloom. Saying that plainly is worth more than a logo on a unified-inbox page, because the gap is discovered in week two either way.

The nine networks mainstream schedulers do not support, ordered by the character limit Bloom enforces. Lemmy shares the 5,000 ceiling with three others but is the only one of those four that also reports engagement.

What Lemmy reports feeds the same twenty-four-arm learner as every other reporting network — twelve hooks, six formats and six time buckets tracked as twenty-four factored arms, which is what makes it informative in roughly a hundred posts rather than over several years. For anything the API does not return, a Bloom short link still carries the click: an eight-character code from a 32-character ambiguity-free alphabet, with per-platform UTM parameters, tying a community submission through to conversions and leads. The seven networks that do return conversations are listed on the inbox page.

How Bloom links accounts across its nine fediverse networks: Tumblr through a one-click OAuth 2.0 redirect, and the other eight — including Lemmy — with a credential you paste.
Lemmy is in the pasted-credential column, with seven of its eight siblings.
05 · The schedule around it

Community posting, paced deliberately.

Communities notice cadence faster than timelines do. A brand that submits four posts in a minute to one Lemmy community has done something socially visible, not merely technically excessive, so the pacing constants matter here for reasons that have nothing to do with API limits.

Ten catch-up posts per tick

After downtime Bloom drains a backlog at ten posts per five-minute tick and skips anything more than 24 hours stale. A community does not get yesterday’s queue all at once.

A 30-day duplicate window

The same submission will not be posted to the same Lemmy account twice inside 30 days — the guard that stops a re-run of a plan reading as a reposting habit.

Slots belong to the brand

A slot is keyed by brand, platform, weekday, hour and minute, resolved in the brand’s own timezone and projectable 365 days ahead. Runway is flagged low under seven days and critical under three.

06 · Where it fits

Lemmy next to the rest of the plan.

Lemmy usually sits in a plan next to its closest sibling and a microblog or two. Bloom composes one idea and tailors it per network — a title-first submission here, the same shape on Mbin, a short post on Mastodon — on one weekly queue and one four-state approval chain. Read the whole loop on the Bloom overview or the eighteen-row table on the coverage page.

07 · Questions

Lemmy questions, answered plainly.

Can Bloom schedule posts to Lemmy?

Yes. Bloom publishes title-first link-aggregator posts to Lemmy, accepts an image upload, and enforces a 5,000-character body limit at compose time. Lemmy is one of eighteen Bloom networks and all eighteen can publish.

Does Bloom read Lemmy engagement?

Yes. Lemmy is one of the ten Bloom networks that report engagement back, so likes, comments and reach come back as data rather than being estimated. It is one of five reporting networks among the nine that mainstream schedulers do not support.

Do Lemmy comments arrive in Bloom's inbox?

No. Bloom's unified inbox reads conversations from seven of its eighteen networks and Lemmy is not one of them — Bloom registers no Lemmy inbox source, so comment threads are read on Lemmy itself rather than shown as an empty list in Bloom.

Can Bloom upload an image to Lemmy?

Yes. Media upload is accepted by eight of Bloom's eighteen networks and Lemmy takes an image, which is worth knowing because most link-aggregator integrations are text and URL only.

How is a Lemmy account connected?

With a pasted credential rather than an OAuth redirect. Because Lemmy instances are independent, each instance is added as its own connected account with its own rate governor, and the credential is stored under AES-256-GCM with a scrypt-derived key.

Post to Lemmy, and know what happened.

Bloom runs on its own application and its own sign-in — an Autocloz account is not required. Connect a Lemmy account, schedule a title-first submission, and read the engagement back alongside every other network in the plan.
