If that was the case, you wouldn't have been accepted, either. Honestly why not let them try to prove themselves as active, productive members. I throw them in the probationary group so that they can prove themselves, and if they don't then they get the boot. No harm, no foul.
And yes, it has come to my attention that some people will mistake those under the probationary group to be a full-fledged member, but it boils down to this; if anyone has a problem with an [elite] member they should contact me. If they don't, I don't care what they think about us, because I don't have the time or patience to think about them. If they do contact me, I can easily make them aware of the situation.
I find the balance of risk and reward to weigh heavily on the reward side of things, personally.
