Okay this has me baffled. I use a particular social site (not myspace, fb etc) for some minor earnings. I tried to log in to my already established accounts the other day and could not get in. These were all created using my desktop pc. Some of these were created using proxies, some were not. I opened up tor and tried again. Could not get in. I tried ghostsurf and could not get in. I went to netzero dial up and could not get in. Wanting to see what was up, I then tried to create a new account using all of the above methods and everytime I entered captcha and hit submit, the site would say, "Cannot create your account at this time". This was all done on my desktop pc. I scratched my head (I usually scratch my balls but that's another story) and opened up my laptop. Using my own ip, I was able to create new accounts but still cannot get into my old ones. WTF?? Other than your ip which clearly has no bearing here, is there any other kind of footprint that my desktop would have left that tells the site not to let that particular computer in? This is weird.
