I will give you some more issues that you should discuss... 1) changed rules and 2) moving of the caps when the price of steem moves up and down.

I see this happen all the time... So on number 1, they should have to publish their new rules and honor them until another such published post comes out. They should also make the new rules effective after 24 hours, that way everyone has a chance to read and react. On number 2, I understand the need to change the rewards as the price drops, so it should a) be part of the rules so that it is clear to everyone (if a price occurs, then you get b upvote)... or b) they should have to publish ahead of time with a 24 hour notice as in step a. Would you like me to give you more ideas? :)
