AAS Meeting Attendee Lists Are Not for Sale
It happens with alarming regularity. In the months preceding each AAS meeting, messages start showing up in members' and exhibitors' inboxes offering for sale a list of attendees with "complete contact details and verified email addresses."
If you receive such a message, you should ignore/delete it: it's a scam.
It appears that the scammers have compiled their own lists of astronomers using publicly available information, such as by doing Google searches and copying contact details from online faculty directories and similar sources. Based on what we've seen, the information is often incomplete and/or inaccurate. In any case, it did not come from the AAS. So, caveat emptor (buyer beware)!
You needn't report the receipt of such emails to the AAS — we get them too, and there doesn't appear to be anything we can do to stop them.
