Amount for October decreased by 4! times

Every month, in the end of the month, google adds me 98% or 99% of total income.

In October, the first time in many years, Google decreased it by 4 times.

Is this may be, or is it a bug?

Oct 31
Earnings (Oct 1 - Oct 31) -
AdSense for Content € (76,5 % only)
Subtotal € (76,5 % only)
Total Monthly Earnings € (76,5 % only)

 

hello guys,
Estimated earnings : X$ And When Finalized 0.25X$

Why it is so and what i have to do?

 

Maybe many invalid clicks?

 

As usually the quantity of invalid clicks is 1-2%.
But now, in October, 76%.... It is impossible, because the same sites are included in account.

Every month it was 1-2%, and only this month 76%! I do not know what to think.

 

problem in google adsense syestem - i lost $215 of my total earnings...

 

I lost $53 on this month and it never happen before that? Would please suggest me what should I have to do?

 

I lost 5%. Something is definitely up.

 

It's already all over the adsense forums. Definitely somethings up with google. I lost 99% of my earnings. INSANE!
