This is why I created a very small image (in size) and made some mod_rewrite rules to display an image with my URL on it, when they try to direct link to anything, this actually has brought me some hits, especially when you get those guys that steal shit from your tgp postings and try to put them on message boards. This way now they just see an image pop-up that says...
You ATTEMPTED to hotlink an image from...
and I spit out my URL
peace,
