I got banned from r/mildlyinteresting like 10 years ago because I posted a picture of an oil spill in a parking lot that looked like a reindeer. Didn't break the rules, no idea why I got banned, every time I've tried to appeal they sent me through like eight moderators and nothing ever got done, and same as you, they don't even reply anymore.

It has been wild to watch such a unique place like Reddit become overcrowded with bots. I feel like it's going to gain legit status as an internet Ghost Town or something before it's finally shot down. Haunted by bots and the weary travelers who aren't aware the whole thing is compromised since they still use Facebook too
