No, not really at all. sounds like you're looking for something like #Hometown or #Glitch-soc -masto forks.
#Mitra is a publishing platform, but it will perform equally well for just #shitposting too if that's all someone is interested in, although I think one would still be better served by masto for that kind of #meaningless_nonsense (it's purpose built for that).
Better still, Twitter!, ("X" now?) I just don't bother keeping up with those toys.
