Problem with my yahoo answer account

Two days ago my level 2 yahoo answer account get banned. I don’t understand what i have make mistake. I was using source link. Is there any problem with using source link?

Looking at the Yahoo Terms of Service and [URL=“”]Universal Anti-Spam Policy anyone other than you can only guess.

But if you read them carefully I have little doubt you’ll be able to figure out what you did wrong.

Thanks a lot for your help.
