[Air-l] dealing with spam and trolls

May I also suggest to folks that they not use their professional/academic e-addresses for listservs. I set this account up solely for the purpose of listserv mail. I also see that I have received the Cornwell spam for the first time but bizarrely giving me the opportunity to unsubscribe. I've heard that some spam works by sending a message that asks you to unsub but in fact you end up actually getting your addressed grabbed and used for even more spam. Truth or urban myth? Rhiannon
