It's not a hack. You probably sell traffic to TH.
Each time someone goes to see TH's support about it, they don't know what we're talking about. Saying they visited the offended sites and they saw nothing.
In other words, they act and play stupids cuz they know what is going on and they do jack shit about it cuz probably they have something to win in all that.
And I'm supposed to believe that they know the difference between a real hit and a bot. LOL
