It's basically that mod's subreddit for bragging and gloating about how he moderates. Every post you see there is him gloating to someone he banned for whatever reason.

For example, when he banned me for asking why comments were being deleted on his ICC spam post, he refused to reply to my message asking why he banned me (see the chat log here: https://imgur.com/a/iGGznUu)

He then immediately posted this post on his subreddit. https://www.reddit.com/r/TrueRandomThoughts/comments/11v8kda/but_but_but_it_was_ok_before_no_it_was_not_you/
