I think that this coin mining is happening in other places, too. My CPU will suddenly start running full tilt for no reason. all I have to do to stop it is go to another tab or page. I've seen uBlock blocking 5,8,13,to as many as 21 somethings on Crowd. They say they have no problems with this, or ads, and no pop ups, but something is going on. Even on TH, which has the https security. I run all my scans and I'm clean. It's the sites, and whatever is going on, apparently it's on all the forums.
