Don't waste your time. There are plenty of other alternatives

First it's an "activity quota" then another flimsy reason to close your account and "suck up" all your previously referred players into their own pot.

Stick to some other program that doesn't do that and make a copy of their current terms and conditions so that you can refer back to it if they try to pull some BS on you later (that was a tip from someone else here). It won't stop all "crap" from happening, but it is a little piece of mind.
