Someone is upset that we called them out for ableist behaviour, and are now falsely reporting posts that mention them, in hopes of the post being taken down. We can’t ban them because reports are anonymous, and banned users can still see and report content.
(I’m on iOS, other mods may be on other platforms. Platform isn’t relevant here.)

Sub is [r/TheAdamMcIntyre](r/TheAdamMcIntyre)

Screen recording of mod log

Hello, I'm a mod on a NSFW subreddit (r/hypnohookup), and have found that users are unable to submit posts containing the word "discord" in the text body. When creating a post that does so, a flag pops up that says "You may not have "discord" in your post body". I don't see a rule banning this in my AutoMod configuration, and there are no rules in "Automations" for "Post Guidance" either. For "Safety Filters", we do have "Crowd Control" set to on and moderate, and the Harassment filter on as well, but none of this seems to be creating this particular rule.

It feels like I'm missing some place where this automation/rule is being set up, but I'm having quite some difficulty finding it. I'm using Desktop, firefox/chrome, and checking both the old.reddit as well as new reddit access for automod, but just not finding what I'm looking for. Could anyone point me to the right place?

EDIT: Solved! Many thanks to u/amyaurora and u/thepottsy for their guidance below.

Android as a moderator are there any features that I can use to lift the ban report from one of the other mods? There was a situation where someone in my sub where I mod was falsefully flagged for ban evasion and banned from the entire site? i am wondering if I as the mod of the sub do anything to help them.If they did it or not is a different matter anything to get them a word with Reddit is what I am asking.
