First of all this is definetly not a PTC site, since it wont pay you for your click. It's an ad exchange thing where you click on ads in order to later on buy more ads for yourself. I remember this site used to pay but that times are like a year ago now. But anyway the site is down right now, not sure if it's just temporarily or for a long time, but it seems that you're spamming the forum with old sites.
