should add blocking features so harassers can't see their target's posts.

How would this change anything, you can write your own frontend in 10 minutes and post from there. Or use CLI wallet, RPC calls, any of the programming libraries...

Option to mute is enough to hide any abusive comments, but blocking users from interacting with your content (or leaving comments) is censorship. Every user should decide for themselves if they want to see content from other users (even "abusive") or not.

a small VC can cancel this guy out or you can set up a Hive DAO and Hraise enough to cancel out any of this guy's votes.

You cannot "cancel" anyone, you can only counter their downvotes. Using DAO against users is censorship. Who will decide if someone is abusive?

With a marketcap so low, any whale can buy up enough stake to ruin the platform for everyone else.

I don't see this platform being ruined for everyone else, only one user. It's Bernie's right to downvote any post as it's his right to upvote any post. It's FREE platform, if you want a safe space go back to Twitter and enjoy being censored if you say something wrong.

If you post to Hive, you don't own or deserve any rewards until they are paid out. I personally got downvoted many times (biggest downvote being $-267.017 from one single vote), but I know the risks for "boosting" my posts with bid bots.

tl;dr: If you are afraid of downvotes, don't post on Hive. And don't take downvotes personally.
