Great job @yabapmatt! :)
But it seems that @themarkymark is jumping onto the idea that I originally introduced via @smartsteem (https://steemit.com/steem/@smartsteem/fight-against-spam-no-more-votes-on-posts-older-than-3-5-days-and-an-offer-to-upvote-services) - without even mentioning @smartsteem or me. Sad.
But I guess that's what I get for not focusing enough on it :)
It's something that's been planning for a while, I don't know much about smartsteem to be honest. We only recently switched to postpromoter as I was planning on writing my own.
I just skimmed your post, looks like you are doing a whitelist, that's not what we are working on. In fact nothing in your post is remotely like what was suggested here (or what I am currently working on that isn't mentioned).
I can assure you, I didn't jump on any of your ideas.
