@PavelASamsonov I've been trying to find more #shitpost / #pooptoot too. So far the best I've managed is following the hashtags in an RSS reader:

https://mastodon.social/tags/shitpost.rss - and separate feeds for #shitposts and #shitposting

https://mastodon.social/tags/pooptoot.rss - and feeds for #pooptoots and #pooptooting.

Hopefully these will take me to my people.
