I was playing on the day I (think) some of this post is referring to, and the admins didn't ban one but two players. I don't know which player this is but they both had long Jewish names. One got banned after lighting some TNT which he didn't actually place, and the other one got banned for doing nothing. The other one returned and got banned again. I think this is the player Ewoksson's post is referring to. No rules were broken and the admins made up some false charges in the admin chat. I will stress that no racial slurs were hurled by the admin team on that day but I have seen it in the past.
This is of course server business, and having bad admins isn't something which has to do with TaleWorlds. However I was quite shocked having watched those players play in spectator mode and while one might be misinterpreted, the other one, who returned after being banned quite humorously, did nothing but play normally assisting his team. I and the chat did protest this as it did seem like the ban was given due to his Jewish name. While this alone is not grounds for TW's intervention, I have seen admins use slurs previously, and they have definitely seem to feature custom skins in exchange for donations, which is totally against TW policy. Also when you have members of NRP/JB/59th (or whoever owns what these days), who have a history of these sorts of problems, it's not exactly unexpected to see them downplaying the issue. They're not exactly going to post logs, screenshots, or anything highlighting their policy breaches.
