FINANCIAL POST - July 21 - A group of hackers gained access to Ashley Madison's data. This is the second time in two months a prominent dating site has been compromised. In May, hackers leaked info about users of Adult Friend Finder. The married people seeking affairs may be more interested in discretion than the average online dating user, but the hack exposes a vulnerability in the growing industry. Mark Brooks, principal consultant at the online dating industry advisory firm Courtland Brooks, said he would be surprised if Avid Life goes ahead with its IPO on schedule following the attack. "Their key value is privacy. They've failed at a key value," Brooks said. "Their IPO is definitely going to be affected. I can't imagine they'll proceed with it. They're not going to achieve full market valuation."
