That's precisely why opt-in practices need to be observed. If you don't want to be in the club, you shouldn't receive texts and you should be pestered to join. If you did join and then you decided later that you don't want to be in, simply replying "stop" will remove you from the program. We actually include those opt-out instruction on every text, because it should be easy to know how to leave if you don't want to continue to receive those texts.

But if you really like a place and want discounts to them, this could be a good option.
