Let me offer a thought experiment. You're moving and need some help. Some dude on the street freely offers to help you and carries much of your stuff. What a nice guy. Once all is well and done and you're moved into your new place, he turns towards you and says "hey by the way, you seem like a nice guy and I'm a part of the local chess club, we're always looking for new members -- care to hear more?" I just don't see how his invitation to join the chess club detracts from his good deed. Even if (for whatever reason) he helps people move solely to get a chance to ask them to join chess club, I still have a hard time finding fault.
