ARRRGGH. Never post late at night.
I know that Charles Stross submitted Githyanki. I know that. Totally know that. Yet, for some bizarre reason, I wrote mind flayer. Sigh.
Anyway, my point still stands. Charles Stross did not create that. His submission was completely in violation of IP of George RR Martin. Granted, it was what, 1981, and no one really cared. ((If my date is wrong, I don't care))
Actually, it illustrates exactly why WOTC won't yoink stuff off of Gleemax. Their TOU could certainly state that I have to pay for legal fees, but, then they have to sue me for it. If I post something that is not legally mine, and WOTC uses it, the legal owner will sue WOTC. Sure, WOTC can turn around and sue me too.
But, it's a bit of a stretch to think that WOTC is going to bother. Why would they? It's nowhere near worth the hassle. They get tied up in court, possibly for years, over something that isn't really their fault in the first place.
So, anything they want to use off of Gleemax will have to be completely vetted before they even try to go into development. That means that they are going to have to contact the poster at some point. If they can't - for any number of reasons - then that material will be off limits.
It's simply not worth the time or effort to try. This is a CYA TOU and nothing more.
