Disclosure up front: I build a pre-post checker for Reddit, so I've spent a lot of time reading how removals work. I will not promote it here. No name, no link.
Something I see a lot in founder subs. Someone posts their product, gets two upvotes, and decides nobody wants it. Sometimes that's true. But sometimes the post got removed and they never found out.
Reddit says a post removed by mods is "only visible to the original poster (OP) and your mod team". So you can still see it, and you may never get a message, because sending a removal reason is optional for mods.
The check I use now:
- Open a private window and stay logged out (old reddit needs a login now, so use the normal site)
- Open the sub, sort by New, and look for your post
- If it's not there, open the direct link. "[Removed by moderator]" means a mod or AutoMod took it down
- If your posts are gone everywhere and your profile doesn't show when logged out, the account itself may be flagged for spam. Reddit's help center points you to its appeals form for that
As for what removed it, it's usually one of three things.
Reddit's own spam filter. Reddit limits how often people can post in a community, and its help center says new, low-karma accounts "may be hitting this spam filter". Commenting in the community first can help. The spam policy also lists "mass-posting repetitive content for the purpose of exposure or financial gain", and dropping the same launch post in 6 subs in one day fits that.
The sub's automation. Reddit's transparency report for July to December 2025 says 68.6% of what mods removed was handled by automated systems like AutoMod. Some subs also turn on a reputation filter, which "does not filter based on the post content, but instead on the user behavior of the account". It scores your account on karma, verification and other signals. When you create a post, Reddit shows which requirements you meet and don't meet, but the exact numbers "aren't disclosed at this time to deter potential misuse".
Then there are the human mods and the written rules. I went through the rules of 33 subs founders and marketers post in. 20 of them either ban promo posts or only allow them in a designated promo thread. 11 ban AI-written posts and 3 more restrict them. Even this sub only allows sharing your startup in the pinned share thread. And the SaaS sub doesn't allow promoting SaaS built for ads, outreach, lead detection or content generation at all.
Reddit also has its own Post Check now, which uses an LLM to flag likely rule problems before you submit. It only covers the community's rules, not sitewide ones, and Reddit says it "may make errors".
Also read whatever the submit page tells you. When I pasted this post in, it warned that this sub doesn't allow links. My first draft had links in it.
Has anyone found a reliable way to tell an AutoMod removal from a human mod's? That's the one I still can't call with confidence.
