After seeing that my friend had no photos shared and that the site was a dating site, I left.
Then, I started getting emails and calls from friends and colleagues. Zoosk had hijacked my email account to send everyone an email invitation from me to see my photos. It went through my contact list - every personal and business listing, and spammed them an invitation to see my photos on a dating site.
I called to complain and get a log of the messages it sent out through my email account, and was given the "I understand your frustration..." message. They said that if I'd read the signup very very carefully, I would have seen that it promised to do this evil deed.
If this is not outright illegal, it should be. It's deceptive, damaging, compromises privacy and security.
