Nah man, sub4sub was around when I will still making my s****y kid videos back 4 or 5 years ago, you know those videos that in your young foolishness you're thinking! OHH GOD, I am going to get big doing this. but yeah, sub4sub has been around for a long time.
I was a mod for a good few years on a site called subxcess, which I actually used to advise people against it (I just loved the chat) , and I can tell you...sub4sub is a dead-end alley you do not want to walk down.
