I like this, but I'm trying to understand the consequences of more than one person using the same one. I think the answer is, nothing until two or more users start to clash. At which point it will come down to who trademarked it first. That sounds reasonable, since you are probably dealing with small use cases wouldn't bother trademarking such a thing. They would get their own unique one first.

One the other hand, I suppose a new type of "trademark troll" could hypothetically arise from paying to trademark these, and then suing you for using them. Although I would like to think that a reasonable defense in court would be, "look I just got it for free from this site, and I willing to stop using it". ... and on the third hand, we see actual out of court settlements for patents that have less to stand on than that.

So I guess it's more of a "who gives a damn", and "quit worrying so much" thing.
