The only change made was adding the clause about making it against the terms of service to abuse the affiliate program with things such as self referrals.
There was no strong consensus that emerged for any other changes.
While not in the proposal, Matt also made a comment that the Splinterlands team would likely not make this back facing, so the all these benefits would apply only to newly obtained referrals, so we only reward new actions that bring in new players and it won't just be a "handout" to existing players.
