This server may look like fun but the admins are jerks and don't let us have any say in anything
It's not like that, the person that you want us to whitelist may not be the same that griefed, but if you don't pay attention to your accounts and let them be stolen by someone you're gonna get unwhitelisted. It's not like we completely don't trust you, but there is proof that nulifies your arguments. We can't put the server in danger because of your whinning about not whitelisting your sister. Sorry without any proof what you say is not valid. It's not just you, that's how the whole Internet and world works.
We had at least 3 or 4 people that griefed on the server until now, though I can agree that a part of the fault is ours, letting our server be griefed, were gonna be more careful from now on. If we are able to track down and ban the IP of the one that used your
sister's account we will whitelist her back, until then we can't trust
you, sorry.
Edit 1: And one more thing: we are giving you the opporunity to play on a dedicated server so don't destroy that. If you want to be the one to judge make your own server, it's not that easy to mantain a server and Nylser puts a lot of work into that I'm not gonna let somebody who just wants to have "fun" (a.k.a. griefing) to ruin his work.
