Platform content rules, verified weekly
Most advice about platform limits is folklore. This is the other thing: every rule here was verified against the platform's own published policy, links to that source, and is re-checked automatically every week. When a source page changes, the rule is flagged until a human confirms what changed.

YouTube
YouTube counts a view the moment playback starts, from August 24, 2026. Plus its rules on reused content, AI video, monetization and strikes.
TikTok
Unoriginal or watermarked video isn't deleted on TikTok - it's made ineligible for the For You feed. TikTok's own rules on reuse and AI labels.
Instagram's API post limit isn't the 50-a-day figure everyone repeats. It's a per-account quota you poll at runtime. What Meta's docs say, plus AI labels.
Facebook cuts reach and monetization for accounts that repost others' work without adding to it. Meta's rules on unoriginal content and AI labels.
Threads
Threads API limits: 250 posts, 1,000 replies and 100 deletions per profile per rolling 24 hours, 500 characters per post, 2-20 items per carousel.
X (Twitter)
X API posting limits: 100 posts per 15 minutes per user and 10,000 per day per app, on top of pay-per-use credits that stop requests when they run out.
Bluesky
Bluesky rate limits: 5,000 write points an hour, 3,000 API requests per 5 minutes per IP, and a login limit that low-volume bots hit first.
Snapchat
Snapchat's Monetization Program is invitation-only: 50,000 followers and 15,000 hours of view time in 28 days, per Snap's own support docs. Checked weekly.
Why identical cross-posting kills reach
The platforms don't punish posting to many places. They punish posting the same file to many places. TikTok makes watermarked or unoriginal video ineligible for the For You feed. YouTube's spam policy names channels that mass-produce templated videos, and its monetization rules require adding "significant original commentary, modifications, or educational or entertainment value" to reused content.
The fix is not posting less. It is exporting clean, re-editing per platform instead of re-captioning, and labeling AI content where the platform requires it. The per-platform pages above spell out each rule with its source.
Common questions
How are these platform rules verified?
Every rule links to the platform's own published policy or developer page and was verified against that primary source. Claims that could not be confirmed against a primary source are either excluded or shown with an explicit awaiting re-verification status.
How often are the rules re-checked?
An automated job re-checks the source pages weekly. If a platform changes a policy page, the affected rule is flagged for re-verification and shows that status here until a human confirms what changed.
Why do cross-posted videos lose reach?
The big platforms enforce originality, not just community standards. TikTok makes reused or watermarked video ineligible for the For You feed, and YouTube's spam and monetization policies target reposted content that adds nothing new. Posting the identical file everywhere triggers exactly these rules.
Do I have to label AI-generated content?
On YouTube and TikTok, yes: YouTube requires disclosure for realistic altered or synthetic media, and TikTok requires its AIGC label for realistic AI content. Meta platforms apply their own AI Info labels using automatic detection.
