1. He provides emails - I think Mark(Guy from Plenty of Fish), really needs to get those voice recordings of Chris threatening his wife online to be more credible.
2. Mark tells a complicated story - A story with mafia and all that, really? If we follow Occam razor, Chris story sounds more realistic. He saw a flaw and reported it. Everything was going dandy until he saw ads for Plenty of Fish data. At this point Mark decides to try ruin Chris by fabricating a story, since he believe it is him trying to sell the data. It is a simpler story.
3. Why isn't Mark contacting the authorities? - A week and Chris is not in jail and responding freely on his blog?
Mark does have some valid points though,he did hack pirate bay: http://torrentfreak.com/the-pirate-bay-hacked-users-exposed-... But Chris claimed again, proof of concept and he has no bad intentions.[What is the appropriate way to expose vulnerabilities?]
In my opinion, he[Mark] should release the voice recording to add more credibility because right now he is sounding shaky.
