Only this:

"UPDATE DURING PREPROPOSAL STAGE: The terms of service will also be updated to prohibit players from abusing the affiliate program, including but not limited to referring themselves to use the program as a cashback system or partnering with others to do so.

This TOS update is not intended to apply retroactively or trap players who have previously self referred their current account."

People want there to be more done to block the "cashback" system. I haven't seen any other realistic ideas to help though.
