If you read back in the thread you'll see that the point of contention was
whether an admin could know what hosts had been blocked by portsentry,
particularly in the case of a 'denial of service' where someone tries to make
the portsentry host block large numbers of dynamic IP addresses.  Equally one
could reference the portsentry logs which will contain similar information.

Adding appropriate accounting rules when blocking would let you know how many
packets had been intercepted without vast effort.
