I do believe the steemmonsters upvotes have been changed so they are good for 50/50, it's all quite complicated though. I will be taking some time next week to properly adjust to all the changes that have taken place. I have some delegations running to daily group upvote account (jumbot, steemraiser) but I doubt that they will be able to have a solution for HF21. I'll make sure @upvoteshares gives at least a 10x self-upvote return and probably will add some kind of dividend payout each time a new level is reached as a way to balance the 50/50. I've set the upvotes at 4 minutes now but from what I understand it just burns part of the curation instead of giving it to the author as it used to be the case.
Small accounts will get hit hard by the HF, it's pretty much impossible to upvote posts that earn <1$ and don't bump it up using bots to 4$+ as you lose out on so much curation upvoting those.
I'm not sure where this will all end, I just hate the fact that the system pushed users to more shady behavior. It used to be about making posts about what you generally love and finding like-minded people in the process to just doing what's most profitable. I hope the platform manages to overcome this somehow but I don't see it happening anytime soon. I hope you stick to it!
