I have a solution for TGPs dealing with cheaters. Btw, I have 2 solutions, so please choose the proper one:
1. Instead of doing robot and live checking all the galleries all the day, why don't you make a script that checks a page 'live' when somebody click on the link on your site?
So, when you approve some submition, you make a copy of it, or just a CRC check of the html. Then when somebody click on some link, script checks CRC code of the target html page 'live' - if it's identical then you send your user to that site, if it's not then just inform your user that this page doesn't exist anymore and delete that link form your site. And your script shoud use a rotated list of Anonymous proxies, so every time somebody click on link, diferent proxy checks the CRC of that site...
2. I am not familiar with IMG SRCing stuff, so can somebody explain it to me if I am wrong... But, what I can think off it's that this thing also hurts bandwidth of someone that is sending it... right? (The Hun in this case) If so, then instead of sending so much traffic that hurts you too, why don't you make a copy of every gallery you approve and host it on your servers, so anybody can't change it?

Ok, that 2nd solution is a joke
but I really think that 1st one could be done.
And I am not defending anybody's point in this post (case). I agree and/or disagree with anyone that send any comment here
But most of post was just bitching about something and very little was constructive about some solutions of this problem... So that's my 2 cents....
P.S. If anybody like the solution no. 1 and make this script, they should contact me about my copyrights for the idea
