On Plenty of fish, how do you delete a man you no longer want on your main page?

I figured out he is a total fake and not real.

You can delete someone else profile but you can report them. View their profile and then click at the bottom "Report User". This will launch an internal investigation by the pOF staff.

You can also block a user from messaging you. In your inbox you can click on "Block User" or select it in the menu of the app. Unfortunately this does not remove them from your search results.
