A post of mine in the bodybuilding subreddit was removed after 55 points and all 29 comments removed because the mods made up an entirely arbitrary new rule that there should be only one post about a recent bodybuilding show. The subreddit rules had no such thing. They just made it up. When I messaged the mods, they banned me from messaging them. Huh? Another example: Apple subreddit allows developers to self-promote their apps on Sundays. I posted an app of mine. Mods removed it and banned me for 100 days from the subreddit because I had 4 comments within the last month and not 5. This is despite me having lots more comments and posts (multiple posts/comments over 7000 points) over 7 years and in last 2 months instead of last 1 month.
