Any lawyers got an answer to that? Hell, I just don't know. I've been told that you can get around a lot of that based on fair use, but who in heavens knows? I guess a lawyer.
I just know that if I get asked to take something down because it infringes them, I'd do it right away, offering profuse apologies for offending them. We're just trying to have a little bit of fun here... ya know?
