YAHOO Answers; Why have my total Answers diminished from 1527 to 1510 to 1508?

You've had some removed (as many here have) for violation, even if they weren't violations. Check your email for violation notices, although the notification system hasn't worked well in recent weeks (notices have been working at least sometimes). Appeal any removal that you don't feel was a violation, at the link below.

Your questions are publicly viewable for anyone to look at,and report..

You should switch your profile to private,like mine.

It's is just the daily numbers all going through some update or some such. Don't worry about it, as it really does not mean one iota of anything, and it will all be fixed tomorrow.

Some Questions could have been Deleted off of the Site that can cause the Numbers to Drop Also if you had any of your Answers Reported and Deleted that too can cause it to Drop

Every time you ask a question you lose points and every time you are reported you also lose points.

maybe they are reported as violations or the questions that you answered were reported as violations or both

Probably because some of the questions you answered were reported/deleted. If the question was deleted, your answer gets deleted too. If YOUR specific answer was reported/deleted, you would have received a message telling you so.
