Submissions without registration/account

Hi, I want visitors to submit classifieds without having to register or create account, I would then review the classifieds before going live.

What I wanted turned out to be a challenge unless I am missing something, if I turn off registration and allow visitor submissions “on” users are required to login for some reason. Anyways I ended up enabling registration without passwords, users would create account as part of submission. This worked for a while, now when one posts they get the below message

“We have detected you already have an account with us. Please login to your existing account to edit/modify your listings. ”

Now when u go to the login, a password is required.

All I want is easy submission where users dont have to worry about login accounts, registrations, forgetting passwords etc A visitor just submits their post thats it. help
