They absolutely did. AOL in particular used a buffer overflow bug in AIM to execute arbitrary code to determine if the client was actually AIM or a third-party client pretending to be AIM.
MSN Messenger and Yahoo IM both cried foul about this and called out for interoperability, but then turned around and denied third-party clients access to their own networks once they got big enough.
