Umm why did my top contributer sticker go away?

A Top Contributor badge is temporary. In order to maintain it, you have to keep answering in the category you were one in. Answering about 30 questions or so per week pretty much guarantees you to keep it for that week, but if you start answering very little, it will simply go away. I, too, just lost my Top Contributor for Yahoo! Answers and Security sections, and now left with only Laptops since I didn't have any time to be on here. Your badge is either gained or lost on Monday mornings.

You might have been seriously reported for abuse or something.

Maybe your ratings went down.

OR you might just be earning less points.

You might not be going on often enough.

It might have been a YAHOO malfunction...ooops. lol

CONSIDER THESE! I am new so im not 100 % sure.

Maybe coz you stopped answering questions for a while and then decided to come back again..

I think you need to answer questions often for it to remain!

Either you stoped answering as frequently or your rating went down
