What's with all the short mixed letter answers by same type questioners? It's on all kinds of categories's questions.?

They are Spammer Bots just posting to Bother and Annoy other Users the only thing we can do is Report and Ignore it

It takes zero effort for yahoo to run a script deleting these as they happen. They can't be bothered.

The site has been under a spam bot attack since Dec. 28th. It is not known who is behind the attack or why it's happening, in spite of some posts laying blame. The bots post an 8 character string of random letters. Oath is said to be working on fixing the problem. All the users can do is report them (if you feel compelled to), ignore them, or take a break from the site until they're gone.

Any time you have a problem on the site, check the Yahoo Products>Yahoo Answers subcategory to see if anyone has already posted about it. You'll find your info faster, save 5 pts, and not end up posting a question that's been asked in one form or another already (as yours has).

Chinese people report them everytime
