On examining /var/log/secure for several firewalls I manage remotely using
ssh I have observed a recurrent pattern of probing over the last several
that attempts to connect using user id's in the following order...

test / guest / admin / admin / user / test


I am seeing this, along with random usernames in large blocks from compromised 
IPs

Is it worth reporting the behaviour to the net block assignees in case they
aren't aware their server might be compromised?

Usually not.  They are generally fools who won't reply, or if they do they will 
blow you off.
