I can't believe what I found, but I've come across an egregious example of abuse of self-moderation on this forum. The user with username "Excimer" has not only deleted some or all replies they disliked, but also completely changed the topic of threads and even moved them to different location. Here is the table of proof.

The proof is right there, so I hope you actually read it (unless you can't read or being stupid). Excimer has deleted about 2000 posts and has abuse at least 20 threads. Some of his abusive thread also shows he have harmed the privacy of other users, so I feel angry no action taken by admin so far. Do not be an idiot and feed him by making any form of reply on his thread. I want to request that this psychopath be banned until Sun is gone and eternally remove every single of his posts and threads.

By the way, I use chatbot to get help formatting the table proof, translate thread titles and fix grammar. So don't be an idiot and accuse me of spamming with chatbot.
