This all sounds remarkably familiar ...

These UCEPROTECT people don't happen to be in Australia outfit run by a
megalomaniac who's name I forget (sorry)

We had an argument when I worked at a tier 1 network. He blocked a whole
/19 address range because he couldn't use RIPE and refused to back down
so I blocked his entire range on the all advertised points
after his business hosting customers could not get to anywhere in Europe
anymore, he backed down.
I must say it was nice to have BGP argue for me since e-mail wasn't working.
Last I heard he had gone bust

Wish I could remember his name

Sorry for the off topic
