A mutual friend of ours got into an argument with him because he made some new friends at his local pub and was buying pints for them left, right and centre. He took serious offence to the suggestion that they were using him for his money (he got about £120k in inheritance after his mum died) and cut both of us off, even though I never said anything to him.
I don't want to elaborate on his backstory but he had a lot of mental health problems and past trauma. After a lot of bad things happened a few years ago, he decided that he was done with life and vowed not to outlive his cats. Have tried to talk him out of it but he's set on ending his own life after his cats pass away.
I presume he's still alive, but I can't get in touch with him as he nuked his phone number and blocked me on all socials.
Mastodon just sucks as a user experience. Your average Joe doesn't give a fuck about federation, yet it's the whole Fediverse crap that harms the UX.
I made the mistake of signing up to a smaller Mastodon instance. Place was virtually empty aside from the lead admin (bit of a pretentious asshole) and a few other guys, and if you decide to browse the All Instances view, you're flooded with posts from hentai reposting bots. And when I saw the #loli hashtag in one of those posts I immediately noped out.
Threads is still in a really bad state well over a year later. Meta still haven't implemented hashtags and trending topics (even Mastodon has these), and my feed is full of thirst traps.
