I'm starting to wonder if someone is 'testing the waters' in China to 
see what they can get away with. I hate to be like this, but there's a 
reason why I have all of China filtered on my routers.

Amazing how much  SSH hammering, spam, and other nastiness went away 
within minutes of the filtering going in place.

There comes a point where 'accidental' and 'isolated incident' become 
"we no care" and "spam not illegal".  And no, i'm not quoting that to 
mock, but rather repeat exactly what admins in China send to me in 
response to abuse reports and blocking in the AHBL.
