How this is measured

Titles must be able to stand on their own without requiring readers to click on a link. d. "TIL about x." and other broad posts don't belong on TIL. e. "TIL how to ..." posts belong on /r/HowTo. f.

Self-promotion
r/todayilearned bans self-promo outright. Product links, launch posts, and thinly framed "feedback" posts are removed.

r/todayilearned posting questions
Can I post links in r/todayilearned?
Yes. r/todayilearned accepts link posts. The usual sitewide traps still apply: URL shorteners, affiliate parameters, and brand-new domains get filtered fast, and promotional links are judged against the sub's self-promo rules. One clean link to the original source is the safe pattern.
Does r/todayilearned require karma to post?
r/todayilearned does not publish a karma minimum. That does not mean there is none: many subreddits enforce unpublished karma and account-age filters that remove posts silently. If your account is new or has little karma, that is the first thing to rule out when a post disappears.
Can you self-promote in r/todayilearned?
No. r/todayilearned bans self-promotion outright: product links, launch posts, and thinly framed feedback posts get removed. The sub's own wording: "No submissions related to the usage, existence or features of specific software/websites". If you want eyes on your project, contribute first and look for communities with a promo lane.
Is r/todayilearned strict?
Moderate, by our estimate (25/100 on our strictness scale, from its measured removal rate, 8 rules, and its stated gates). About 3% of recent posts disappeared within a day in our sample. Strictness is about enforcement, not hostility: a strict sub is predictable if you follow its rules.
What is the best time to post in r/todayilearned?
Based on our sample of recent and top posts, activity and scores peak around Wednesday 1am UTC and Thursday 10pm UTC. Treat this as a starting point, not a guarantee: a post that breaks a rule gets removed at any hour. The heatmap on this page converts these windows to your local time.
Why do posts get removed in r/todayilearned?
The most common reasons are self-promotion violations, plus the layers every subreddit has: Reddit's sitewide spam filter, unpublished AutoMod rules, and account-level gates like karma and age. In our recent sample, roughly 3% of r/todayilearned posts disappeared within about a day of going up. Many removals are silent, so checking your draft first beats finding out after.
