Users then subscribe to every newsletter under the sun and await their checks.
I would assume that some members are receiving checks. If they weren't, word would get around pretty quickly. This is a common complaint I've heard from publishers.

You may want to sign up for your own account, do a bit of investigating about their set-up and the attrition rate of members who join your list, etc., before going this way.
