There are other technologies that counter that.
I was banned yesterday, by some puke phony conservative that doesn't believe in the first amendment. It took me all of five minutes to log back on.
Also, there is the problem of young kids, fresh out of school with Libslut tendencies, running TH. They were brainwashed for 16 years or so in Lib ideology. They cannot bring themselves to ban the likes of Sybil or USC or rikker.
On the other hand, they are easily led by crusty old wh ores, older that their grandfathers, who have nazi control freak tendencies.
