I use adblock too, so I dunno if they even display ads. I figure their profit is from either ads or spammers buying captchas, or both. I get a bad vibe off of all of those that are just clones of one another. The lotto one doesn't bother me as much, so it's the only one I use regularly.

I hope these sites aren't related to coinbox itself, because as a micropayment system it's a good idea, and I don't want it to get a bad rep.
