You need to contact Craigs List.
They can do more than anybody else and a lot faster.
I had a troll pasting on Craigs lust and I got a ton of pictures from queers posing nude.
Since the dude was using my email address in the ads, they gave me his info.
I tracked him to his employer in New York and he got fired.
Craigs list acted quickly to tear down the ads.
But Craigs list has a real problem with their loose posting control.
