What bonuses did you mean? I check the first post and as well as the last posts but I never see a bonus being posted there. I don't know if maybe the OP removed them now because I am seeing some complaints after doing some backreading. If those are juicy bonuses then it can surely lure the players into signing up and trying them, most especially if the requirement are not that tough to complete.
If only they operate properly then I don't think there will be people who will complain. It's also their fault so they should not try to avoid it. Locking the users account isn't also a solution or will make them quite but it actually worsen the the situation.
I think he was referring to the no deposit bonus that Neodice announced a few weeks ago.
Note: We have just launched the no deposit bonus feature and are still testing it.

I don't think $9 is a particularly "juicy" bonus, but I'm sure there will still be some people who try to take advantage of it. If the requirements for earning the bonus are not too strict, it's likely that there will be a fair number of people who try to abuse the system. For example, if you can get a $9 bonus by simply signing up for and verifying your account, then it's not too hard to imagine how people could game the system by creating multiple accounts and getting paid over and over again.
