click on photo and on the left hand side it says BLOCK
Click on their profile and hit block. Make sure to report them for harassment. Hell, share the user name! I'll report him.
go to their profile, on the left side there is a list of things on the bottom of that list is block. sorry you're having problems.
Like everybody else said....and if they create another profile just block that one too. it takes longer for them to make a new profile than it does for you to block them so if they are persistant they will give up eventually.
yes keep shunning yourself. turn off your cell phone. be a creep. be a loner. eventually, jump off your building block! better off...
go on their profile, its down the long list of pages on the left
