Yup.I think these clicks are invalid..(from the same IP)

 

may be anyone in home click on this ads
but could this close my account

thank you for your help

 

I have seen this happening while using AdBrite where every legitimate click earned me $0.
I stopped using them.
Don't know about AdSense.

 

this is invalid click..yesterday i got click without revenue

 

how the clicks become invalid?
i know there is click or there is not

 

It can be either fraud click or public service ads
