Currently, if users have a registration on website they can post their comments without login too, only using their email address. In this way registered users' avatar will be shown on the site. If any (anonym, not-registered) users know their email address they can post comments like a registered users' (or admin) using their avatar.
Is there any way to dont allow registered users to post comments without being logged in? Error attention? or any way?
On my site registered and unregistered users can be able to post comment. There is no way to hold all comments for moderation, or required registration for all users. Thx
