I got permanently banned from a subreddit after posting a picture of my dirty cabin air filter.
I questioned the permanent ban, but I never threatened or insulted anyone. After the exchange below, I got muted and told I was reported to Reddit security for moderator harassment and I would be kicked off Reddit entirely.
I’m posting the full conversation so nobody thinks I’m leaving anything out:
Reddit:
Hello,
You have been permanently banned from participating in a subreddit because your post violates this community's rules. You won't be able to post or comment, but you can still view and subscribe to it.
Note from the moderators:
“Banned permanently for violating Rule #6; No spam posting, self-dealing, PSAs, promotional linking, or posting content that is totally off topic. Linking to outside content is allowed only if it's in answer to a poster's question and germane to the current discussion.”
“If you have a question regarding your ban, you can contact the moderator team by replying to this message.”
Reminder from the Reddit Admin team: If you use another account to circumvent this community ban, that will be considered a violation of the Reddit Rules and may result in your account being banned from the platform as a whole.
Me:
“What? I don’t understand my post had a lot of likes was on topic (vehicle maintenance) the frame of a friendly reminder was just a random way I framed how to show how bad my air filter was
So I don’t really know why it would be removed”
Moderator:
“That’s not what the sub is about. It’s a Q&A sub you posted a public service announcement that no one asked for.
So that’s considered spam”
Me:
“It wasn’t a psa it was just a post of how nasty my air filter was. The title was just a random title had 0 to really do with the post I thought it was better than something like ‘look how nasty this is’ or ‘um hey guys I guess I did a thing’. I think a perma ban for a post that had like 150 likes and had good discussions going on is kind of ridiculous.”
Moderator:
“Your opinion is not noted. You’re still banned.”
Me:
“Is there no appeal no time limit?”
Moderator:
“What would be the basis for your appeal? It’s pretty obvious you don’t agree with the rules. We’re not going to change the rules. The rules are in place to keep the sub on focus, which is only questions and answers. There are other Automotive subs that let you post whatever you want. Feel free to post your experiences there.”
Me:
“Ignorance and the fact it wasn’t a psa”
Moderator:
“Ah, so not only don’t you follow the rules, but you also like to get kicked off of Reddit completely. So you’re now muted so we’ll never hear from you again, and you’ve been reported to Reddit security for moderator harassment.”
So my question is: how does a moderator harassment report actually work on Reddit? Do admins manually review the messages or is it mostly automated? I’m trying to understand whether this is something serious or just something mods commonly say after a ban dispute.
