You might try this:

To block AIM, you should filter for incoming connections from port
5190 from AOL's servers and the login server login.oscar.aol.com.
To do this with ipchains:
ipchains -A input -b --sport 5190 -j DENY
ipchains -A input -b -s login.oscar.aol.com -j DENY
To do this with iptables:
iptables -A INPUT --sport 5190 -j REJECT
iptables -A INPUT -s login.oscar.aol.com -j REJECT
