@stateofarcher in terms of advice w making friends, i'd argue the big two are discord and reading and commenting on stories! if you're reading a story you love and commenting, the writer might reply back and i suppose by repetition of that youd establish a friendship!
i have a tiny discord server if you were interested in joining, the link is on my message board! there's only four of us in there but everyone's super nice!
if you're looking for moots, i think complimenting accounts and following works for some people
