I don’t use any social networking and haven’t for years, maybe a decade.
I did have a Myspace account once. I see that is still going, sort of, but my account is long dead.
I was on FaceBook for a time and had many real friends. I posted pictures and news, but eventually left. The advertising got intrusive, the scammers were a daily occurrence and, while I posted stuff, many of my friends did not, making it unfair and a bit one way. And my best friend on FB died, and that was a blow.
After I left, a couple of people, folk I had known for decades, got very nasty. Why had I unfriended them? I hadn’t, I just quit. They have refused to speak to me since.
Twitter was just the same with more hate and fake facts. I lasted a week.
I also looked at Bluesky, but really wasn’t interested. Can’t tell you anything about any of the others.
