Looking at the "trolls" I can't see any trolling. I see people criticising the conference for fair reasons that they care about, and trying to be helpful after initial snarky tweets.
This is not trolling. And I absolutely agree with their criticisms.
What were the original tweets that caused so much trouble? I've tried to gather what I can but I don't see much 'trolling', just criticism, some polite and constructive, some less.
And there's a few tweets by @britruby that have been deleted.
This checklist seems very centred on the UK hackday format (which I very much enjoy). I've noticed US hackdays have a somewhat different culture, with different expectations, as do gamejams, etc
