Mods should be in-house, on payroll, and strictly bound to the network’s standards.
This should generally be less of an issue anyway in a system that actively penalizes the sorts of crudely expressed, un-nuanced posts that are typically social media’s bread and butter. Not being able to appeal to basal emotions (“it feels right” is a poor metric) and being required to substantiate views more intelligently takes the air out of a lot of fringe sails.
Yes, it has to, because trolls and haters are relentless. The choice of whether or not marginalized communities are allowed to ban abusive posters is fundamental because moderation resources are finite.
Of course, there are many who believe that marginalized communities should not be allowed to moderate posts and should be willing to absorb a constant onslaught of abuse as the price of existing.
One also needs to keep in mind for spaces for marginalized in particular are more sensitive than typical because they have to keep their shields up at all times because of how much more likely attacks are. If making them feel like they can safely drop their shields is a goal, then incidents like people posting in an antagonistic and/or harassing manner needs to drop to background radiation levels.
But even after they flee, it won't be enough — the new platform where they took refuge, having become popular, must be stormed. Any room where the marginalized congregate must be filled with the din of hatred. In short, it is not enough for Musk-era Twitter to be Twitter — BlueSky must also become Twitter.
BlueSky is already quite bad like old Twitter, though not like X. It's not filled with Nazis, but it is very bland and corporate with no substance.
