@zorinlynx @david There absolutely isn't serious abuse coming from tech.lgbt. It's a quite calm place filled with quite decent folks.
This is all just a "principled" display of loyalty between various members of a community now famous for their heavy-handed moderation and blocklisting tactics as a means of exerting control on the parts of the Fediverse they don't directly control already.
Those same principles don't apply to larger instances like dot-social, who they still permit despite a huge subset of problematic users coming from there, simply because they're worth too much in terms of business to lose.
It's all just leftists-eating-other-leftists except manifested in powerful people who can sever tens of thousands of connections at a moment's notice and use that power to grind their personal axes.
