I don't think people understand how spicy #Upscrolled is going to get. The CEO professes to have a "once it's not illegal" policy. Even if you have enough mods, that's not going to wind up great.
They seem to have no cap or rate limiting of registrations and are "blowing up" at the cost of a Discover feed that's got some fairly fucked up shit in right now. Gore, porn, propaganda for extremist groups, plenty of bigotry. If it was on fedi I'd have it blocked.
