I want to be able to create an account without providing an email
I bet whatever instance that doesn't require emails will be defederated for spam. Just use a burner email or an email mask like firefox relay.
Like SimpleLogins. It allows you to create an email on the fly like mudskipper.lemmy@relay.com that you can create an account with (in this case the lemmy part of the email is taken from whatever company you are signing up with. All emails sent to that email will get forwarded on to you. If the account sells your email to spammers you will know exactly what company sold you out and you can disable that email address. Same thing if the company itself spams the hell out of you.
It's very handy! Only con I have come across is some companies will not accept the address. For those i just move on or create a burner Gmail account.
the instance hosted by you is going to be the most privacy friendly.
you have to trust someone else in any other instance.
