Opinion on key drops

I see that some people will just paste the key itself when doing key drops. I think this is totally a bad way to do it, because people will just claim the keys blindly, and there's a (fairly good) chance it'll be a game they're not interested in, therefore, they might never play it, and, then, they had taken the chance from somebody who could be genuinely interested in the game.

Also, all of them are most likely claimed by bots when dropped like that (I don't know any, but heard about it).

Personally, when I see a key drop that's not identified, I don't even try it, because I have so many games already, and just a few I would be interested in, but that's just personally.

So, what are your opinions on that?
