Nigero,
We have a lot of cheaters and abusers and we need to be able to find people, even when they are offline.
When you want to play with an unrecognisable name like qqqqqqqqqqqqqqq or kgjdjfdf you make it very hard for admins to catch cheaters, not saying you are one.
So we have to make sure we recognise you next time, and with a kick we have a history to recognise you.
About other players, when we search a name, it will give all result where that name is part of, so if someone uses i.e. name tpl it would give thousnads of hits, because its part of eTPLayer. The names you mention doesn't have that problem.
All we ask is to play with a recognisable name, and this forum is for discussion, not in game. So, no drama needed.
