Alexxis,
A couple of points:
1 - Tor sucks. It provides more of a sense of anonymity than really exists and it is dreadfully slow.
2 - Like ASPD ECCIE has decided to block anonymizers and their websites. This is done by blocking many of the known IP addresses from these groups. You can log out and back into TOR, get a new IP address from a new exit node and you should be fine. As for why any site with potential liabilities to the authorities would attempt to block anonymizers and keep logs of the IP address every time someone logs in... well, let that one percolate in your head for a while.
3 - If you are serious about security you should talk to some of the people who've posted on here that you feel know what they are talking about. Most people who care about privacy and internet security are more than happy to share their knowledge with others.
