[squid-users] prevent squid being used as spam passthrough

Is it possible for a proxy running on port 80 or 8080 to be used as a pass
through or zone origination for spam email?
We have had some users sign up with email addresses such as spambot and
other stuff recently. I suspect these are just bots signing up around the
web but got me thinking whether a proxy could be used in a chain or tunneled
somehow and whether that could be blocked?
