You are not allowed to click on your own ads.And also viewing your own page again and again will also prompt you as an invalid publisher.So also dont refresh your adpage too much
You are lucky they just warned. Many publishers banned without any warning. So, please be honest with Big 'G'
No one gets banned without Warning from google . If you have got warning then remove all illegal traffic + incentive Clicks served on your pages and all that stuff
Yeah, also sometimes they just say that when u don't do anything bad.. I had same problem with bidvertiser some time ago.. They had ban my account because suspected clicks when i didn't do anything. So i went madly to their support, opened a ticket, and fortunately they re-opened my account with all the balance in it.. Also, google is very strict..
I second that . It depends upon the extent of the fraud clicks , the greater the fraud the most likely to get your account banned without warning . Usually warning are given to those publishers who click their add one to three times daily intentionally.
Not Good News .. try To contact them and explain for them what happened , of course if you didn't click have A good day .
Wahahaha, you'll be banned in no time. Just kidding. I haven't received such or a similar message as such. Just stop clicking your ads, that's the only thing I can say about it.
