A lot of these reports are invalid, and the ones that are valid already seem to be taken care of. There is one report that bothers me (being sniped through a wall despite rules against wallglitching, which was rejected for "no evidence"), and aside from that, the only thing that really bothers me about XE is that when handling reports, from time to time the administrators will act like immature brats and call reporting players the n-word (the only word that actually DOES seem to be censored on this forum, and for good reason).
Is that reason enough for them to be delisted as an official server? That depends on what the other beta testers and maxo believe. Personally, I'd have to see more evidence before doing so.
