hi can some 1 tell me how i block a certain person

hello i am trying to find a way to block a certain person from contacting me as this person will not leave me alone and has started to harass me at all hours of the day/night i have told this person that i do not wish to talk but this person will not take no for an answer it is getting beyond a joke and really pissing me off if any 1 can help to either block this person or if the site admins can remove this person from the site i will be happy in both ways

I am not doing anything
wrong ok
you are the one harassing and being offensive

I am only wanting a friend

give me achance don't swear lets chat
I still wish to emailyou my picture if that's ok

not sure what the issue is tasha seems nice enough to me.. remember you can just ignore her if you are so against talking to her theres no need to ask she be banned. just relax and ignore her if you must
