You better forget that account. It's really hard to get that account back for Yahoo Answers. You can try new one.
yahoo account of his now very strict management and found that spammers will be closed off, if it is determined he did not create waste, may bring an action to the customer, will be re-opened after confirmation
They are really hard to reach and generally don't give a positive answer, just create another one and be more cautious.
Just create another account. It is hard to get it back. My solutions is just buy a yahoo answer account. There is some people who provide it.
Ive made around a dozen Yahoo Answer accounts, sold a few and kept a few but the point is you can make quite a few with no IP ban and no problem!
We can appeal only for if we got deducted our point but if our account has been suspended then there is no chance to get that back.
If you are really worried about getting suspended, try to be a bit more subtle with your advertising. Try and actually provide a helpful answer while at the same time dropping a link (that is related to answer).
