Yeah, I told them not to click anymore, under any circumstances, even if they liked an ad. It's been like this for 2 days now.
Really? I did not know this, do you mean to say that if some person came accross my site and clicked on my adsense repeatedly ... I could get banned or in trouble? If this is true its kinda scary (Im not saying your wrong) but think about it, doesnt that mean that anyone could ban a google adsense user if they wanted to?
Yes, that is correct. Click-bombing is the major worry for Adsense publishers, and it's something that Google don't really seem too keen to offer any tools to allow publishers to protect themselves from. Click fraud is what gets publishers banned though. The algorithms Google uses to detect the difference is of course a closely guarded secret.
