How do I start an investigation on my YA account?

IDC about your willingness. Why don't you ask

"A Simple Question?". 

Keep Your Question To Yourself 

I have no clue sorry, ******

Hiw many questions have you asked. You lose 5 points fir each question, not 10, you loose 10 points for each question or answer that is deleted, regardless of whether you are emailed or notified. Sometimes you lose 20 points for each deleted question or answer because you did not appeal in 7 days. THAT may be what happened. You GAIN 2 points for each answer. You do NOT lose points for answering. You get 10 or more points for each .best answer. Yiu get 3 points for each best answer you CHOOSE, but you ha e to wait at least 1 hour.

The Reason why your Points are Dropping a lot is you probably have had a lot of Questions and Answers Reported and Deleted Its -10 Points for Each Question or Answer that gets Deleted

Just a thought, you don't seem to fully understand the categories of this website...

This should actually be in the Yahoo Products page; I'll put it into the correct page.

I've lost some points for issues here and there...just keep going and doing a good job....you'll get to whatever level you want eventually...

With 70 violations, that would be 700 points...I guess its possible but unlikely you'd get that many at once...but it is possible.

Seeing that points are meaningless and hold no value, why would you waste your time. Just visit here or not, it really doesn't matter.

it could be a glitch or sonneone rpeorting it, i would check your ennails, theyre starting to send ennails now again
