How do I delete this wall post?

[iheartgoldblum]

This person wrote on my facebook wall talking a bunch of trash using expletives and so forth then proceeded to block me. So everyone else on my friends list can see it but I can't. It's just invisible if I look at my own wall. I can't report the person cause they've blocked me and it's not even on their wall. Is there any way I can delete it so my mother and other people won't see the terrible things this person wrote?
