There are some forums that I myself have been a member of, some have offered if you want to choose to disconnect your email address to your account. There is a reason why nothing is safe, if a hacker should come across the database and that someone, for example, email@example.com registered at his personal email address, it can be bad for the forum. I am from Europe and here Europe is very tough with GDPR and what you can store from people. But that is a bit briefly explained by what I mean and not my question about GDPR. Is it possible to have such a function that if you want your email address linked to your account or not? I know there may be problems with password reset but that's another issue. Maybe someone who can do an add-ons?
