While my primary masto is a single user instance, basically anywhere else I exist on the fedi is a subset of infosec dot *.
Those instances are all run by someone who a) is cool with spinning up a whole bunch of instances, b) is willing to risk the costs, and c) is excellent at delineating policy. There’s a “no fucking threads full stop” instance, and a “no threads by default, but user can flip switch” instance, for example.
That’s a method of operation that works from my pov but doesn’t suit everyone’s needs. Personally, I want nothing to do with threads but am more able to express my anti corp tendencies than I was in my twenties, and I’m more willing to accept that “it’s just bandwidth, find the instance that meets your needs.”
My needs involve no threads at all, but I can accomplish that with a very small amount of effort given. My circles.
