This method is very good and is suitable for frequent IP replacement. I have collected it.
IP replacement? What did you mean?
That link is for bypassing captcha when you tried to log in.
OP may have not exeggerated his ordeal... If i remember very well. It took me over 15 minutes to get registered through Tor only for me to be shown a banned IP address message.
