Probably could have earned a lot more from his exploits if he went the formal route and directly confronted Twitter. But then who even knows if Twitter are a good 'first responder' when it comes to high-profile exploits of their system.
There was a recent post about some researcher who exposed flaws in Tor's architecture (which allowed third parties to detect Tor traffic easily) and Tor's staff didn't respond; so she published the finding without going through the proper channels, both embarrassing Tor staff, and simultaneously strengthening the Tor network.
The 'I'm going to publish this sploit because you didn't respond' is a good tactic and I want to see more people do it. It's just unfortunate that the various channels like HackerOne[0] or wherever the skiddies flock to these days are not utilized thoroughly.
