I'd like to think blacklists like this have warded off more bad actors than interesting community members. No way to know for certain, but with 26k+ on this particular blacklist, I figure there must be some other quality content being crushed in the mix. That or they’ve already left Hive forever despite have something worthwhile to offer.
I’ve always wondered why blocktrades delegates so much to the account. Maybe he thinks it’s to protect the blockchain. It’s something we may never have an answer to, like a lot of things that go on around here.
