I think it's funny how some people think that having an online handle is somehow protecting your identity. Finding out who someone is through their online profiles and such is not as difficult as most people think, it just requires more than pushing a button or using a search engine. This is especially true if you use the same handle, even if it isn't your real name, on multiple forums or different platforms (IE your forum handle is the same as your XBox Live and PSN names). I don't think there's anything wrong with people using a handle, whatever their reason for it. You can still hold someone accountable for being stupid online even then, unless your idea of holding someone accountable is going to their house and beating the crap out of them. At that point, it's usually just easier to report them or ignore them.
