if you're going to remain friends with someone who's been ousted from a community, because you want to be available to help them reform themselves, preaching about how much better your approach is vs. cutting them off does NOT HELP
that's the road i usually take and part of taking that road means you have to respect the boundaries of other people and not treat them as less valid just because you think it's less kumbaya than what you personally have the bandwidth for
my relationships with other people are not detailed on twitter to begin with, they are not tools for extolling my virtues on social media, and if you believe in reformative justice, they shouldn't be for you either.
