I have seen quite a number of organisations using /24s that they have 
pirated from various places. Worst culprits seem to be small access 
providers who change upstream providers and are too lazy to renumber 
their corporated network away from the IPs that have been reclaimed. 
They stick in a NAT and then ignore the problem for a few years.

One particular company insisted that their pirate IP block be routable 
within the shiny new core network causing endless headaches making sure 
it doesn't leak into their BGP.

Another ISP is even using oops-I-thought-that-was-RFC1918-addresses in 
the vicinity of 172.50.x.x and pirate space from 6.7.8.x for their point 
to point links.
