In retrospect, judging from how the mastodon/fediverse milieu has changed for the worse over the past month, I've scrapped my plans for self-hosting an instance.
It'll simply be too much work, and the off-chance of having to deal with the kind of people / dumpster denizens the run fediblock or have taken to doing dogpiling for sport here in Fediverse is a complete turn-off for me. It is simply not worth the effort.
