I was suspended a year ago. For months I would get emails how my answer was picked as the best answer. I got suspended for using the same answer a few times. Funny thing is so many people were too stupid to search the questions first and were asking the same question over and over.
Just create a new Yahoo account and move on. It isn't worth complaining.
Yahoo will delete your account.. and after you make so many more, they will just keep deleting them even if you havent answered a question or posted a question with the account.
That happened to me and i was posting genuine answers and not putting my links in answers. It sucks too because I got some good traffic from there.
