I'm with you here.

The fact that posting content costs money, is enough to avoid any blocking or muting.
What's going to happen if someone is being an ass and starts porting shit? He/she spends all the money, the content doesn't get rewarded and gets buried down against the good content.

I really don't see the point of blocking when you have the payment to do that automatically for everyone.

Just like a boy wouldn't survive much, unless it spends lots of sats to post shit. There's always a cost for being an ass, and that's a good thing.
