This probably do not happen often but sometimes we just have some yahoo account that would be better off deleted than left inactive. My Yahoo account for about 10 years just recently got closed. All you have to do is go to account termination link make sure you are logged in to be able to terminate the yahoo account. For me, it was a hard decision and been given some thought for sometime. Why close an account? Because it is better closed and not able to be tempted to open it again. This way the account is gone for good!
