Безопасен ли moz.com?

Moz got in touch to say that the spam message wasn't posted by them, but rather it was a message sent by someone representing a website to which they have assigned a Domain Authority score of 50. The Domain Authority score (a search engine ranking score developed by Moz) of 50 is something that the spammer obviously thinks is pretty good, so it appears that Moz aren't taking spammy behaviour into account in calculating the score. I think that that is a weakness. As Moz have at least got in contact, I've increased my rating from 1 star to 3 stars. ***** Original report: I got a message through the contact form on my web site from this company telling me that for a fee, they would "advertise" my web site.
