Should I accept this invitation to conference PC? 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.
If your alarm bells are ringing, but the offered position is attractive, then there are ways to check it out without causing problems.

Example: The person who's name is on this invite will have contact information outside this particular email. A phone number or email that you don't get from this email, for example, but from their institution or some such. That way, if the email is not legit you are not going through the channel it has provided. Contact that person using that independent contact info. The approach could be something like so:


  Hello well-known-person-running-a-conference. I have received this email inviting me to join the PC for well-known-conference. What would be involved? How much time and effort is expected to be required? What other requirements are there?


Then if the person responds with ready information you can simply decide if the amount of work is acceptable. If they respond with "who are you and how did you get my name?" then possibly the original email is not so legit.
