Unfortunately, I can not create ysm account by myself. Yahoo immediately disable my new account without any reasons. And send me message with "We have found suspicious activity on this account..." What activity? Why? their dont explain.
in addition , you may use adcenter from msn and adwords from google for another way. donnt tell me adcenter and adwords banned you too.
if you sign up for one and immediately Y! detects suspicous activity, then if you buy an account and they might still detect suspicous activity. where are you signing up from ? if it is some cyber cafe or school computer, then it might be problem
