What is your email used for when signing up to Lemmy? Is it just for password reset?
We use it as an (imperfect) speed bump for spammers. Also for password resets. That’s about it.
I assume it can be seen by admins?
I trust my admins, but I still used a forwarding service because there’s always a risk of an attack exposing data. Unless there’s some other security there I don’t know about
Yes us instance admin can pull the email address form local users.
Can you pull for foreign users? Curious what other federated instances can see
select person.id,name,local,local_user.email from person join local_user on person.id = local_user.person_id where person.id =2;
id | name | local | email
----+-----------+-------+---------------------

Email is only available for local users and only if filled in on the signup form
