This is where I'm coming from. I can block accounts that are clearly trolls, but if I block them in one instance I can't watch for them in the communities I moderate. So effectively, I can't block them and I can't do anything to discourage them from broadcasting disinformation. There's no option for negative feedback other than to feed the trolls by replying to them.

I'm finding it has consequences that were most likely unintended, enabling the worst people to appear as though their toxic opinions are praiseworthy.
