r/cscareerquestions does not publish karma or account-age minimums in its rules. Subreddits often enforce unpublished filters on top of what they write down, which is why posts from new accounts can vanish without a message here.

Only in the designated thread. r/cscareerquestions restricts promotion to monthly stickied thread (1st Sunday); a standalone promo post gets removed. The sub's own wording: "Promotional or advertising threads are only allowed in the monthly stickied threads.". Post your promo there and keep regular posts value-first.

What gets removed in r/cscareerquestions

Self-promo outside the designated thread
Promotion is only allowed in monthly stickied thread (1st Sunday). A standalone promo post gets removed.
Low karma or a new account
r/cscareerquestions publishes no karma or age minimum, but unpublished account filters are common at this size. New accounts should comment before posting.
Reddit's sitewide spam filter
A separate layer before the subreddit ever sees your post. New accounts posting links, URL shorteners, and repeated domains are its favorite targets. Removals are instant and silent.
A shadowbanned account
If the account itself is shadowbanned, every post looks live to you and invisible to everyone else, in any subreddit.

r/cscareerquestions posting questions

Can I post links in r/cscareerquestions?

No. r/cscareerquestions accepts text posts only, so a link-only submission is rejected at the door. You can usually mention a link inside the body text, but the sub's rules on self-promotion still apply to it. Check your draft against the rules before posting.

Does r/cscareerquestions require karma to post?

r/cscareerquestions 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 That does not mean there is none: many subreddits enforce unpublished karma and account-age filters that remove posts silently.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/cscareerquestions?

Is r/cscareerquestions strict?

Relaxed, by our estimate (20/100 on our strictness scale, from its measured removal rate, 11 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/cscareerquestions?

Based on our sample of recent and top posts, activity and scores peak around Thursday 6am UTC and Friday 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/cscareerquestions?

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/cscareerquestions posts disappeared within about a day of going up. Many removals are silent, so checking your draft first beats finding out after.
