db0 and Unruffled have both been banned for reactionary behavior and, in the case of the former, DM harassment.
Due to these irreconcilable differences we thought it only right to allow the community to weigh in on defederating immediately.
According to this person “tankie” is anyone that criticizes the privilege of white westerners in the imperial core who have been privileged and comfortable their entire lives off of the backs of colonized people.

As always, use 
to vote for federation and 
to vote for defederation.
Stay fed’ed. “Posting isn’t praxis” yada yada, yeah, but there are plenty of radlibs who call themselves anarchists that are ripe and even open to being properly radicalized. When hexbear gets cut off from other instances, it makes it all the less likely that well-meaning radlibs will have a chance to see good, genuine leftist takes, which does influence them (as many have outright said.) Dbzer0 serves as part of the pipeline from radlib to actual anarchism and/or communism. Defederating effectively caps the pipe at radlib and we shouldn’t do that unless absolutely necessary to protect BIPOC/trans/neurodivergent/etc. users here. And I think it’s safe to say dbzer0 as an instance is far from being a danger in that way.
This is a pretty convincing argument I say it should at least come with some concessions from the admins there though.
Asking for concessions from contrarians is silly. Much better to just leave them sitebanned so their worthless contributions impede fewer interactions.
