AFAIK Tynon doesn't delete accounts. They also haven't banned anyone, to my knowledge, in quite a long time. It's up to the strong players to push them out of top10, which will also get them out of Palace (only top 4 can be there). If the big players aren't helping with that, well that's a bit of conflict-resolution that needs to be done ON YOUR SERVER. If you are stronger, you can fix this yourself. Lemon squeezy.
