Have you raised a support ticket? I'll bring this to the attention of our Net-Ops guys but normally the best way to have us request removal is to raise a support ticket. We had some problems with a spammer over the weekend which could well be attributed to this.
Edit: problem ref: 58107.

Bob,  I thought I had raised a ticket but on checking it appears I didn't.  As you have now flagged this do you still want me to do one?

[#5]

Nope, should be all sorted now

[#6]

Yes it appears to have been sorted.  Thank you Bob.
