Want to know if someone has blocked you on Badoo? Even though you can still see someone's profile, you may still be blocked. Only private profiles are hidden, but being blocked on Badoo means you are restricted with how you can communicate with the Badoo profile in question.
Try commenting or doing something on their profile, and see what happens. Is it still there when you refresh? How about when you log out and log in again? If it doesn't pass both these tests, you are blocked!
