a couple minutes ago I cam across @deathwing's post on RCs, a great start:

There does need to be some limits though, such as it being an account <60 days old in my opinion.
It can also potentially be limited to certain transactions I suspect. For example, comments and posting, but not submitting teams. Not sure how fine it can get though.
