So? If I'm being harassed and I filter out innocent Steemians then that would be my choice? It wouldn't block the IP address from accessing Steemit.com, it would only block the IP address from accessing my content on Steemit.com. If I don't want people behind certain VPNs to access my content then i should be able to block the entire IP range if I choose.
The point is to make harassment inconvenient, it's never going to be impossible.
