I try to clean up Anon chat whenever I see it, but considering the limitations of that place, it's mostly a fruitless endeavor.
We would have to sit on anon chat 24-7 constantly moderating it, and maybe in a month's time, it'll start to clean up.
The problem is the "Anon" part. When people lose an identity, most people tend to turn into this creature that takes joy the the pain and misery of others.
