Since this is a distributed network and there's not a central authority 
to rule on each incident being legitimate, the only way to stay out of 
the politics is to ignore people's abuse complaints. Someone's SSH 
server is being spammed with probes?  That's pretty low bandwidth, not 
much threat to the network from a cracking script.  Maybe you don't like 
it, maybe it's criminal or whatever else, but ostensibly it's some 
paying customer's traffic and it should be delivered unmolested.  When 
someone's infrastructure is getting packeted or having their routers 
crashed repeatedly, they respond to that, usually without having to be 
emailed, because it's actual abuse of their network.  A lot of this 
other stuff is just people abusing the abuse contacts to get someone 
else taken offline.  Phishing websites fall into this category - it's 
not network abuse, it's just content someone doesn't like, and one way 
to get it taken down is to threaten the network that carries the traffic 
for it.
