Dunno about Yahoo or ICQ, but I helped a friend block AIM. AIM gets tricky:
if you block a port, it tries another. e.g. - if you block 5190, the
default, it'll try 80, which you most likely don't have blocked.
I had him block login.oscar.aol.com at the firewall. That nukes it. If you
run a local name server, you could also be sneaky and setup a domain for AOL
that redirects requests for login.oscar.aol.com.
That's one way, anyway.
