I think it's like spam email. The same people send the same junk from different domains with different names and email addys. You can't block them all. Same thing here, someone would have to actually read the posts to determine it is spam. Even if they blocked the poster, they come back through a different door. It doesn't appear TH is going to keep staff on 24/7 to screen posts. I used a rather benign term, rhymes with slap, and was prevented from posting. They have a program that does that for them.
