I did. But the one I joined had some like fucker running it and would spy on people's private messages. Couldn't say shit about the jews. I got kicked out a bunch of times and said f it.

I have an account on mastodon.social, but I’ve hardly used it.

Mastodon is as good as the people running your Mastodon instance. One Mastodon instance could be a censored wasteland like most of social media while another could be open and free. It’s what you call a federated protocol. You can talk between instances, but each instance has control of its own domain.

No. Avoid the fuck out of it. I won't say why though.
