Le site rs6.net est-il sûr ?

Received email saying my Google Search Appliance "Contarct" is expiring. I don't have a Google Search Appliance. The URL displayed in the email was ***** but the actual link goes to rs6.net. This appears to be part of the Constant Contact business. CC might a legit business but they are helping spammers.

rs6.net belongs to Constant Contact a bulk email provider aimed at organizations wanting to manage their email news letters and announcements. They are a professional organization that has good terms and conditions. They also seem to enforce them. I am sure that if you receive spam (after trying to unsubscribe) or phishing email, they will take corrective action. Blocking the account or removing the phishing content. I have rated this site questionable for "suitable for children" because it hosts many different newsletters some of which may be adult in nature. Adult because they discuss sexuality and issues relating to sex or explicitly sexual because that is what the authors of the newsletters want to talk about.

Constant Contact does not fully police all their clients, a small minority of whom are abusive. People should use caution. One bad client used CC to push out a Amex phishing page: http://r20.rs6.net/tn.jsp?f=001W20POS1yzwPJ_IaMvHzNFpIwTiyQl8oopPtyJfIvesatUZlcrI-YK4brDzz8C8sC-95NbbynuFk-uC7IbhzdxI2L-39XSzZDBZBQrXRIaSlCJwMhLi5Ak0eOleR-Q6E7wnesQ8gi9henx9CNDzJRVScKAkgrETRCYSoxsHcIFP9abM-pMlNQbgSThjaugqpPWiHf0UdiuBs=&c=vif1ikvwaQ2A42wvazOV7nBpH5o4tgxJXO8iW-Wz3lmnFACcSTc3Dg==&ch=DWMrgBFPe1ILknUZhrhb5srs1WVxK8OoGsVQ1uiPsBWt6BFh4fHl5Q== which redirects to this phish URL: ***** This and other similar problems have been reported on the phishtank, such as this report: *****
