again, we don't have any connections to facebook. im using the do not track me plugin for firefox, and i can tell you that there is a twitter widget, google analytics, and viglink, and that's it.
it's more likely than not the plugins you are using are misleading you. i recommend using donottrackme, adblock edge, and better privacy. don't use ghostery, it claims to help you avoid tracking but actually reports to tracking companies on better ways to avoid plugins like ghostery/donnottrackme, etc.
This couldn't be farther from the truth, not to mention impossible. There are literally hundreds of thousands of TOR exit node IP addresses, and they are constantly changing. It would be extremely difficult to block even 10% of them. There was one incident where someone was using TOR to harass StP (the fact that you brought this up in the first place tells me you might know who this is) and i ended up banning like 10 of his IPs before he gave up.
