GitHub: Block the Bullies
This is a very good feature, but I am also afraid it will make Zed Shaw and others think that his attempt to out-troll the trolls and multiply internet drama was a force for positive change. "If you throw a big enough temper tantrum and incite a large enough shitstorm, developers will address your concerns" is an unfortunate precedent. The fact that controversy and negativity attracts eyeballs and can trigger improvements is understandable, but it also creates perverse incentives.
