Is it possible for a normal user to post a new topic or reply anonymously?
P.S. By anonymously I mean without any publicly visible reference to their name / account etc.
It would be ‘ok’ for a staff (mod/admin) to see who posted it but not the normal visitors or registered users.
The trick here, first up, is defining what you mean by “post […] anonymously”. It’s a much more nuanced thing than you might first think, and there are a number of different things people mean by it.
By anonymously I mean without any publicly visible reference to their name / account etc.
It would be ‘ok’ for a staff (mod/admin) to see who posted it but not the normal visitors or registered users.
It would also not list the posted topic/reply on the user’s profile.
Yes, that is possible. Enable the allow anonymous posting site setting and users can switch to anonymous mode to post without associating it with their user account. Staff can’t quickly link an anonymous account to a user, but could if they wanted to dig into logs and the database. Normal users will not be able to connect the account to a “real” user.
Actually, you can, but it’s logged as a “show email” action. Go to the single admin user page and it shows up where Google / other associated logins would be.
Edit: Of course, side channels (posting time, writing style) can be used, as you see on 4chan etc, but these are mitigated by only using a particular “anonymous account” for a max 24 hour period - once that cycles, the number increments again and you lose public linkage.
