I agree that becoming too associated with nazi trolls (which are uniquely a problem in a way that even other sorts of extremists are not, because of the paradox of tolerance) is a huge danger to nascent platforms. I’m not sure what to do about it either, except maybe to continue trying to promote the platforms even despite the risk of offending them in hopes that they can grow faster than they lose reputation. And in the case of Peertube, defederating from instances hosting hateful content, I guess.

By the way, this…

implying that all lgbtq+ people are p*dophiles, which is a completely fucked and cruel thing to say

…is actually an understatement. What they’re actually doing is engaging in the equivalent of blood libel and trying to incite a pogrom.
