What does it mean on facebook? (opinions)?

[john]

I would like to ask your opinion about changing your relationship status from 'Single' to 'Blank' (relationship status not stated) Please give your opinion by stating:

1. In what situation would you do that?
(For example; you are in a relationship, you want to be 'off the market', etc.)

2. Do you agree that changing the status from 'Single' to 'Blank' is the first step you are going to be in a relationship?
(For example; you are now good friends with your crush, you are going to be in a relationship soon etc.)

4.Please state any other reasons as well.

3. Are you male of female?

Thank you in advance.
