I left Reddit because of mods in certain subs I frequented. It seems like they just decide someone broke a rule and you get banned from several subs at once with no explanation. I never had any warnings or contact with the mod team until after they banned me. I appealed to the platform and was accused of harassment so I deleted my account and never looked back. I was honestly shocked when it happened.
I spent some time Googling and settled on Lemmy because it had a familiar feel to it. I chose Mastodon because of its similarity to the old bird site.
Elon has some nerve calling out someone for making money of bettering humanity. That's the very definition of "the pot calling the kettle black".
