Correct Solution:
This is a social problem, solve by policy. Any violators of the policy
to be severely punished. Firing the first couple of offenders helps.

Technical solution:
Firewall everything off, allow only white listed sites (easiest way).

Difficult solution:
STFA.

Block *.chat.yahoo.com
Block *.msn.com
Block *.aol.com
Block login.icq.com

Use a proxy like squid to prevent the use of http tunnels (recent

You can use an iptables script for this(archives).
