Welllll--you could look at at this way, too: SO WHAT if a MP item has some bogus restriction (for commercial use only if you blow me first, or whatever)? IF they see your "unacknowledged" work somewhere (and what are the odds), and IF they bother to track you down (ditto) AND if they actually have the balls to give you a hard time, you can always tell them to screw off (go ahead and sue me--let's see you show a jury how you've been damaged). I certainly wouldn't look through all of my dl's to double-check. I don't really get the free-stuff restrictions, either--give it away or don't, but don't hang a bunch of meaningless conditions on it. I always assume that "non-commercial use only" in free-stuff means "don't say it's yours and sell it" and nothing more.
