Is It Possible...?

A participants best answers is based on the percentage of ALL questions answered divided by best answers. So if one has a 100% best answer once they answer another question the 100% will Drop to like 95%. To keep a high percentage, don't answer anymore questions Unless you know that you're gonna get a best answer. The percentage for best answer is not based on HOW many questions they asked.

It could be that someone is "pointgaming" by having two accounts, one to ask, one to answer, and giving themselves the Best Answer -- that is easy enough to see if you click on their profile and click their "Best Answers" link on their Answers tab -- that will show you which questions they got Best Answers for and you will see if they are mostly from one particular person.

On the other hand, it could be someone who was once a high-level person that was suspended and has made a new account to get back on -- in that case, they may really HAVE a lot of good answers to give due to being on here earlier.

You just never know!

I agree with Yahzmin. If you give the link to that persona profile we can have a look at it.
