I have been on site 2 times, first time made to level 6 and was booted, then this last time to level 3, and they didn't like how I answer questions on security, finally insult is after I was violated my account still is voted on and made top contributed in security. go figure. Its a site were there is no real person to talk to, on a web site to e-mail, they claim they will answer in 48hrs, took them 6 days the last time and then to tell, they will not reinstate my account, I must start over.
I found this site, much better, don't plan on going back but I did send a letter to the president of Yahoo Inc.
