tl;dr of the reports of a cop instance going around Show more
The admin of hackers.town recently posted https://hackers.town/@thegibson/101693197693941092 (cw: glancing allusion to prison rape) - a sampling of slides from a presentation in which they identified themself as a "Proud Member of FBI Infragard".
For those not familiar, InfraGard is a non-profit "partnership between the FBI and members of the private sector" that "provides a vehicle for seamless public-private collaboration with government that expedites the timely exchange of information and promotes mutual learning opportunities relevant to the protection of Critical Infrastructure", according to its website (linked from https://en.wikipedia.org/wiki/InfraGard which says much the same).
As you might imagine, a great many people are upset that a large fediverse instance is being run by someone who describes themselves as proud to be involved in the funneling of information to the FBI, especially given the long history of FBI informants being made to infiltrate left-wing groups for spying and entrapment purposes. See for example https://berries.space/@undyne/101694112267233862 from @undyne.
I think that probably gives everyone enough context to make decisions.
