The only way to reactivate your Yahoo Answers account is to appeal and win the appeal. In the email you got about your account being suspended, there should be a link about the appeal process. Good luck!
you can actually appeal, if yahoo answer team found that you are not against any rules, then they will reactive your account
Yahoo Answers appeals can take time, because there are so many Yahoo Answer members. And appeals are rarely successful.
You can apply to yahoo admin's. I think if you are not suspended any major problem then they must reactive your account.
Your account has been suspended? Well, the only way i am thinking is you should contact Yahoo. I am sure that they have given you fair reason/s about your account being suspended. Message them about your counter demand or a self explanatory about why they should reactivate your account. If not, just create a new account. Good luck!
I think there are very less chances of getting it re-activated but possibilities are there so for that purpose you can contact Yahoo. If there is no response than go a head and create a new account
reactivating yahoo answers account is really tough. i lost my password and i cant but create a new account later...
