@chronohart @snarfed.org the only reason I can't imagine it being a problem is because it's so completely manageable... if I get too much trouble over the bridge? I block the bridge.
Starts coming through over a different bridge? Another quick and easy block. And mind you that they have to find a bridge to harass me over and they get what... one harassing post before they have to go find another bridge? That's alot of extra work on their part as bridges aren't that plentiful.
That's before getting to the array of other moderation tools available, well before talking the tools available as a server admin.
On top of that, their opt out system is fantastic, just by a simple tag dropped in my profile block all bridges using this software? Hell yeah, that's a great measure and I hope it catches on elsewhere.
Altogether... I'm more worried about people already here than people accessing through a bridge. I think there are more self-righteous people here than any other platform.
