I see the discourse about QTs is roiling right now, and just some food for thought:
QTs already exist on the Fediverse. Pleroma implemented it a while ago. Getting QT'd has lead to me having to play whack-a-mole with malicious instances telling me to unalive myself, because they weren't happy with my antifacist takes.
The most powerful tool I have here is the block function. This alone has halted dogpiles, and I never had to involve my followers in it.

Now, I know, I admin my own private instance, I have the unilateral power to defederate, and I definitely wield it
But anyone can block an instance from the account level, and more people should take the liberty of doing so.
Nothing undesirable from hubzilla!
@Alex I agree. I think defederating from entire domains should only be used if trolls, spam & haters overrun an instance.
Aside from that, account blocks should suffice—or even limiting a domain too. Latter should only be used if an instance is struggling to fight against trolls, spam & haters.
