Spam message: "Confirm Your Cvent Email Address". From the message header: ***** ([204.239.0.224]). From the message header: ***** ([204.239.0.224]). The IP address traces to Cvent Inc. (cvent.com), which agrees with the specified domain. This is an actual business that's been around since 1999. Problem is, they use spam as a marketing method. I guess the whole point of the message was for someone to verify an email address that they already had.

Received unsolicited email email promoting event through this site. Can't tell if it is a rogue customer, or if they are complicit. I would have given them the benefit of the doubt, but there is no easy way to contact them about abuse; their contact form requires all sorts of detailed information about you (phone number, email, city, state,zip, etc,) in order to submit questions, and JavaScript must be enabled for the form to work. Because of this I'm marking them down on trustworthiness, though I don't have detailed information about their validity.
