Número de usuários e posts legados

in /about, one can see the total number of accounts on the forum. Does this number include:

  • deleted users? I suppose not.
  • anonymized users? I guess not either but just checking.
  • suspended users? According to my test, yes.
  • deactivated users? According to my test, yes.
    (but I’m unsure how the counter is updated.)

If it does include suspended & deactivated users as I think it does, is it possible for me to achieve that:

  • Obsolete users accounts are impossible to login with, but their posts are not deleted;
  • And they are not counted in the total number of users?

Also, could their posts be preserved, but also their username on each post? (sort of a new option between suspended and anonymized if you see what I mean. It would be great to know who posted something even though the account doesn’t exist anymore.)
