Ooh, that's easy: just look at the crap they spew towards the peering
fabric. :-)

Right. It does give complications wrt. trouble-shooting connectivity
though. Switch port up but no traffic (L2 black-holing), a single L2
provider with a loop or misconfiguration causing port security
violations on all of their customers' ports, communication channels when
those problems come up, etc. Having said that, so far it's still pretty
manageable.
