actually there are ways to deal with these type of individuals.
the only reason they are so bold is that they believe they are shielded by a veil of anonymity. if someone were to unmask them by finding the individual’s name who operates the server, they would most assuredly shutdown immediately. having to be held responsible for one’s actions is a sure way to get them to STFU.
as long as they believe they’re anonymous, they will be dicks. this is the same reason we get TK’ers and doorblockers. but if someone were to identify them individually, their behaviour would change 180 degrees instantly.
one could also take the approach that they are just looking for attention – so why not give it to them. contact a newspaper/tv reporter in holmdel, NJ (home of the ISP that is operating that server) and tell them about a hate group operating an antisemitic game server in their town. reporters love that stuff.
this has nothing to do with political correctness, this has to do with being responsible for one’s actions. if one wants to push antisemitic views, there’s no reason we have to let them do it anonymously. lets see how committed they are to those views once people know their real names.
