Well it seems that my Subscene.com has joined the number of sites utilizing COINHIVE. at least they're asking for permission and making the users choose which is considerate of them.
I allowed subscene to use my CPU to mine since I've been using the site freely for years now. And I'm not on the site for a long time anyway. I stopped folding@home before and didn't even bother to mine for coins since electricity cost here is absurd.
