Dope, there are just a couple of TGPs which have "don't redirect traffic" in their rules... usually there is nothing about redirect or just something like "do not change your gallery after submit", which is not about redirectiong...
So, you should point your question to TGP Owners, why the start screaming about cheaters BEFORE they change their rules in the way which makes redirectors cheaters.
You should change your rules first (put "do not redirect" sign there) and only after that you can try speaking about cheating...
Althought, usually don't need to agree with TGP rules to post a lik. Theire is no some checks boxes (like "I've seen rules and agree") or just a note "do not post if you do not agree" in those rules... so, it's just something like a list of things which tgp owner doesn't like. Well, that's his own problems if he doesn't like something, right?
It has nothing to do with cheating. Make
correct rules/terms, this increases chances that people will follow them...
If all of the TGPs will put "do not redirect" and "if you push submit buttion you are agree with those rules" in their rules, then I'll agree with you, that actions of tgp redirectors are looking like a cheating.
But even if they really become cheaters (not only by the words of tgp owners, like it's now), then they are still far less cheaters, than tgp owners, which put links on tons of unlicensed content, hotlinking servers, stealing bandwith, lieing on the boards, etc...
I think TGP owners should think about changing their behavior... their current behavior is pretty stinking.
