Last week I decided to upgrade on one of my favorite PTC sites and it was pretty much a waste of my money. It did come with ads, but other than that, I was not happy with the results. I didn't notice a difference in my earnings at all, not only that, it was pretty expensive to upgrade for a week! During 2 of the days of my week upgrade, there were NO ADS to click! Another waste and disappointment.
Needless to say, I will not upgrade on this site again! Very disappointing and very slow admin response.
