a whitelist/blacklist should be managed by consensus, not one guy / exchange ( => corruption).
You're missing the point. If it were managed by consensus, how are the extortionists running this "Operation" going to get their money?
This whole thing has NOTHING to do with cleaning up shitcoins. It's about scamming people out of money. Scam coin creators like the OP clear out the competition. Pool operators get sheep to DDOS competitors. And the extortionists collect their "registration fees."
It's not about cleaning up anything. It's about criminals working together to expand their enterprise and conning fools into doing most of the work for them.
