cool so that's a CTR of 185.71% google does NOT filter invalid clicks automatically. this is absolutely nonsense. perhaps google CAN filter invlaid clicks automatically, but that doesn't change the fact that they ban publishers and tell them it was because of invalid clicks. every webmaster earning significant revenue from adsense MUST protect himself/herself from invalid clicks. use uniqlicks or adsenseclicklock or some other system to safeguard your account. it would be great if there were some other system that can deliver the high profits of adsense, but there isn't, so protecting your adsense account from invalid clicks (and termination) is essential.
I don't think you can do much, invalid clicks automatically gets rejected by adsense on any suspicion of fraud/bot clicks, so you don't have to worry about it, though as mentioned above, you can contact adsense to convey your concerns
I wouldn't worry about it, You can't stop a person from clicking your links so you should just let it be, google will take care of it. If you're clicking your own ads, google will find out, if not, dont worry about it.
