Haha, I feel like I've explained this about 100 times now, but hey, what's one more?
I'm strongly against internet anonymity. Internet bullying (which trolling turns to far more often than people care to admit) is a very real, very damaging thing - I've seen people self-harm as a result of internet bullying.
Solution? Removing the anonymity of the internet. I don't say anything on AP.net I wouldn't say on my Facebook, and I don't say anything on my Facebook I wouldn't say here - so why not keep them as closely matched as possible?
You realize message boards are the lone standard for a non-personal-pic-avatar, yeah?
You're acting like attaching your real person to this account is what keeps internet bullying (presumably from you) to a minimum. It doesn't make sense. If you're against bullying then you shouldn't need some kind of negative incentive to not do it.
