Blocking the person is the best move, I think. Don't be apologetic about it either, just block anyone that bothers you and don't worry about it.
How do you do that? I have some people that message me in the chat section and they don't get it.
(1) Go to YOUR
Profile Page; (2)
click on "
Modify Profile" (tab towards the left side of the screen, and just above your avatar picture). (3) Then scroll down the short menu to
click on "
Buddies/Ignore List". Just
above the "Buddies Center label, (4)
click on the "
Edit Ignore List", and in the window that opens, (5) type in the member name that you would like to ignore, by
entering the name in the "
Add to Ignore List" slot, which is near the bottom of the page.
Hope that helps
