Admob september high invalid traffic?

Hello.

It appears admob took a big this month (September) with high invalid traffic i.e An order magnitude compared to previous months.
Anyone else seeing this? This is happening after low cut in august than usual.

I got unusual high traffic in admob the last few days… but in Revmob an equal the same unusual high traffic.

The things, in admob and revmob only affects one game… In google analytics is not represented, but in google developer I can see a Not-so-much but high increment on installs…

Did admob reduce the amount “Invalid Traffic - AdMob Applications - AdWords Ads” around september 11? This time it seems to significantly high compared to last months.

You can find it under Settings -> Payments in your admob account.

Yes, I see that as well. But I have almost the same numbers for July. In August Admob reported almost no invalid traffic.
