I prefer OAuth generally. Why? There've been too many data breaches already. If anyone has to have my data, it's better off with a known company with proven security techniques than...some guy. Also, I'm lazy and paranoid about password managers (being on a strange computer and not being able to access my account 😱), so I only use email and password for accounts that are really valuable and run by trustworthy services. Also, OAuth providrs also indicate what permissions you're providing to the application, so they can't do something sneaky behind your back (ideally).
For further actions, you may consider blocking this person and/or reporting abuse
