I was a little worried myself. No problems now that I can see. It takes this problem to a higher level though. The obscene pics are disgusting and make FReepers with children afraid to surf here. The bigoted threats are very disturbing and even if there is no serious intent behind them it calls to mind the worst atrocities humanity is capable of. Very disruptive. The addition of an actual attack on the machines of FR members perpetrated through FR servers demonstrates a willingness to actually harm others in a substantive way.
Combine those things and the concern that this cretin is more than a mere perverted prankster starts to become a much more probable reality. At the very least he's willing (and doing) intentional damage to others property. It's a real short step for someone like this to take this dementia out for a drive and inflict it directly on a human being.
It could be a stupid kid who's crying out for someone in his life to take him seriously as a person. It could be a stupid kid/adult who's sending out a rattler's warning that he's about to become the monster he's been imagining himself to be.
Would make people leary about checking FR from work on their lunch hour as well. Sigh.
