Can you link me to some?
Try searching for feats for one thing. Heck, even the Hypertext SRD contains material which violates the OGL. I forget now which, but, I do know it's there.
I know of at least one site that published every feat from pretty much every WOTC book out there - Dandello's Realms Help pages
That HAS to be violating something. But, it's been up for years.
