On social media, putting the burden of blocking on a million users is naive because:

• Blocks can be worked around with bots, someone has to actively fight circimvention.
• Some users don’t have the time to block, simply conclude “this is a hostile environment” and leave.
• Some users fall for scams / believe the disinfo.

Experience has shown that total freedom is a suitable policy for apps that support 1-to-1 conversations via short text messages. Everything else invites too much abuse. If it’s public, it will have rules. If it’s totally private, it can have total freedom.
