Sellings flags is a dead business-model; you should have paid attention to what happened to those who tried that as well.

Except we are not selling flags. I still advise to have a look to the post.

Credits that have no value.

Credits that have the very same value as liquid STEEM / SBD sent directly via transfers, which value is determined by the amount of delegation and number of bidders.

aka leeching off from work of others

The automated whitelist is custom code which is not implemented in postpromoter, if that is your guess. Still, the advise is to read the post.

themarkymark has been working his ass off to create such a blacklist - you're just taking the credit. Good job!

The blacklists are not based on themarkymark's only but on the official Steemit blacklist which is a combination of various blacklists on top of allowing to add more via a PR. https://github.com/steemit/redeemer-irredeemables

It is understandable you may not know how that works, considering what @smartsteem is pushing to the trending on a daily basis.

Before attacking an initiative that tries to do better, do better yourself.
