apparently fosstodon has some kind of a "no politics" policy in place? that's a very big warning sign!
to see why, i suggest watching "How to Radicalize a Normie" from The Alt-Right Playbook.
if you're super pressed for time, begin watching at 8:35 and stay until 12:30.
that part of the video explains very clearly how having a "contained" fascist on the mod team is still part of an effective recruitment strategy, and why the way mike (the instance owner) is acting now is a sign that the strategy is working.
but i REALLY think you should watch the whole video, because it explains not just what communities with "no politics"-style policies does for the alt-right (the "no controversy" kind that gets you a warning for saying trans lives matters), but also the rest of the alt-right radicalisation pipeline that those communities are part of.
