I already have to put up with seeing stuff about Ebola all over social media sites and news stories. Stupid rumors, irrelevant information, and conspiracies. If I hosted servers I'd ban you you for talking about it just because I'm sick of loving hearing about it.
or you could be reasonable, and tell them to stop, and if they were smar they would, because you're the host, but you know, you wouldn't get to ban anyone in the situation, so it's irrelevant.
I don't have a problem with Ebola jokes or whatever I only have problems with the crybabies who say Ebola jokes are sick, when it's not even a major problem righ now.
