Most of those thumbnail tgp's are illegal. Not the tgp itself but the people submitting them.
Almost every content provider out there gives you right to display the images on a set number of servers. You dont have the right under your contract to submit your pics to other websites. Hotlinked thumbs are ok but you cant display images you dont own on your server unless you own the rights to the picture. Unless its written in your contract. Im wondering why more content providers dont crack down on this.
P.s. im not dissing your tgp , im just stating a fact that most people arent aware of.
Also under u.s law you cant display images that the age of the person is not clear. ( this means those closeups on bald pussies or photoshoped images making girls look tiny are illegal and basically qualify as cp ) I know this is a touchy subject for some. And i am a little bit concerned with the catfights ad that GFY displays . Looks like a 10 year old girl.
