Have you read the discussing for the wapanese page?
These people clearly understand what they're doing is wrong (like posting personal information and being racist) but the fact that they're doing it on the net, they feel like they're not doing any harm.

The thing about this is, if the spotlight turned to them instead of the people they mock on their site, they would realize how bad it feels to have your face on a page with text degrading you.

There isn't an article there about me, but I've been mocked before so I know how it feels.
