This question is especially for people who have joined in the last week. Have you used other fediverse platforms or is this your first time really using one? What do you think of it so far? Are you aware that you can comment on Lemmy posts with a Mastodon account?
I don’t really understand this complaint. It’s the same as an e-mail account? You log in to your instance and don’t need a log in anywhere else, you just post / reply on whatever you want from your instance.
It’s a question of trust and stability. If anyone can spin up an instance and collect user emails and logins then there will be some bad actors. You have to trust your native instance admin. With many potential instances in a new platform it’s hard to know what you can trust. Also you could join an instance that can’t pay the bills and you lose your account.
