Well, your site ain't the only site having problem from this tool.
But who on earth would waste 5 hours each day clicking while he can use this tool and click all ads.
some people says it's illegel and i agree, most of sites says IT'S NOT ALLOWED.
But that sites can create anti cheat for it easily but they don't, because it's good for work that SOME members click all ads so the sponser's site gets clicked faster / more so he have to renew it and the owner earns more.
There is some sites i'm not using this plugins for even tho. i can use them.
your site is one of them as it's cool and simple, Not like other sites which eats your time.
I wish you understand and you can ban us ofc, it's your site lol xD
