That's just what I tried to tell them in an earlier post on this thread... I guess people just tend to panic when they read a network's Terms & Conditions, because that's just what I was seeing in this thread.
Its not necessary to contact their system will do it all who is guilty or is innocent since they have been from long time. For your satisfaction you can contact them. n those clicks are from other so no need to worry much about it. Good luck ! Dont worry be happy,earn money
I've had something similar happen to me too. The money wasn't added to my account - so I assumed Google knew that the clicks were invalid and such. I'm not exactly sure (I don't speak from experience), but I have heard many stories of people getting banned for having too many invalid clicks (even if they weren't from themselves). Hope your issue gets resolved, and I would also recommend contacting Google.
