Great ! but watch out ! we don't want that Lemmy take the same path as Reddit did ! ( hopefully this is limited as it run as a ~Federated model )
Anyways, I believe to avoid censorship and jeopardize users privacy the following should be considered by Instance admins and moderators.
Avoid as possible a mandatory email to register
Doing so is not reducing spam or whatever you're afraid !
It's limiting users to create account that preserve their anonymity !
If you don't know why anonymity is important I'll suggest you to dig this website to start with https://www.laquadrature.net/en/support/#chiffrement
BTW if I couldn't be anonymous, I wouldn't write any post on Lemmy, as I'm not living in a free country !!
Look on other instances some admin have found clever way to circumvent bots without the need of an email.
Also Lemmy don't require too much of moderation ! as any user can use the block feature in their options
so you should not censor content in behave of others !
If the freedom of expression is limited to the ideas that we like, it is not freedom of expression.
