I have to say, from the writing alone Chris Russo sounds a lot more confidence inspiring than the POF people. That long rambling blog post by POF did not come across as very professional.
Yeah its sounds like Frind in his panic over the active exploitation of the vulnerabilities by other hackers felt like Russo was trying to blackmail him because of his lack of command of the English language.
He was probably trying to communicate that he was looking for a consulting position after finding the exploit trying to be helpful
The serial killers are a quote from the mail of the wife of POF founder, I think?
The Russo side does sound "insecure", as he admits himself. Presumably they have not been in business for very long. But that is not the same as infantile, it's just inexperienced.
I wonder where the discussion of "murderer" or "Russian mafia" first came up, seems totally unrelated to the incidence and random for anybody to bring it up first. Could be some kind of pronunciation miscommunication like "member" -> "murderer"
err what?
