New users get adsense account and then click on their ads so google kick on their ass and they say adsense is bad.
No 1, google adsense started adsense for referral and immediately retired because of they offered $250 for that who earn $100 was funny for me cause some of my friends started to referral account for their relatives and drive traffic until they get $250 + $100 = $350 from each $100 earnings ... google took time to understand that trick, but my friends bought Ferrari. 2, why google cant detect and remove the earnings from invalid clicks or just disable significant risks sites instead of ban their account ? anyone can make invalid click on your site or anyone can make significant risk on your site? that means someone can ban your adsense account ... you cant block them even Google cant do it, You are not safe. 3, google bought dubleclick.net its the END of adsense because they are dumb like cookie collecting and serving ads base of interest based ads ... interest based ads means they are collecting our privet data and searched logos to serve ads on our PC. it will be funny if my kids play online game witch i dont like but they are using my PC in most of time after my office time i come back to my home and try to search best holiday packages but ads are online games like "prank maze" Don't Put All Your Eggs In One Basket ...!
