When you receive 2 GB bandwidth just in couple days with average page views, someone got to be blocked. Here is my list:
138.145.242.6
164.68.168.5
195.92.163.130
205.237.46.254
217.23.225.120
sorry, unless you guys can give me good reason what you were doing, i’m affraid i’m gonna keep you on my list.
Have you tried to trace it? Probably search engine’s crawler anyway.
