Why yes, pinging is evil and can result in slow servers.  A simple, but
illegal DOS (Denial of Service) attack is the 'ping -f' on a UNIX
machine.  This sends out as many pings as your modem OR processor can
handle.  When this is implemented from a machine that has a very fast
internet connection, the victom's computer can be knocked off the
network as a result of trying to answer all the pings.  I even had this
happen to me when I was on IRC and someone didn't like my handle.  They
didn't ping my server, but my dynamic IP - not to say that they couldn't
have gone after my ISP.
