I have received an e-mail inviting me to join the program committee (PC) of a well-established and renowned conference in computer science. The e-mail looks genuine, based on the sender address and the links provided to accept the invitation.
However, I do not directly know the guy writing to me (though he seems to be a respectable researcher, after I googled his name), and the e-mail is not tailored at all on my profile: it looks automatically generated, and does not specify at all why they chose me.
Is that normal, or should that ring some bells?
Thanks in advance.
