Sending out unsolicited email. Looks like they're trying to gather as much information as possible for unknown reasons. The fact that there are some positive entries here with extremely vague comments leads me to believe these guys are astroturfing and can't be trusted.
Unsolicited email based on my client's website ownership data. SPAM email soliciting business based on assumed website content. Phishing for data to add to their website. I black-listed future emails from this untrustworthy site.
