I never got the joke

Regarding the style of including "evil" as a part of one's LJ name... having never gotten that particular joke, I find it to be a minor irritation. Past advice to me has been "if something online annoys or stresses you, don't read it." But I have no idea what I can reasonably do to avoid having to see this particular irritant in my inbox, coming from several others... other users can call themselves whatever they please, and it doesn't seem quite worth defriending and comment-banning the affected individuals. At least, the ones that I haven't already delisted for other reasons...
