I know a few journos, decent people, who get constantly harangued by twats (because they work at the 'wrong' paper) and I can see why they get fed up. But then others are just pure ego. I got blocked by Owen Jones for 'wasting his time' (!) The guy's an absolute tool but I generally avoid picking fights these days. People just automatically think you're a social calamity who doesn't get out much. I think there's also a wider understanding nowadays that there are lot of mentally unwell people and cranks with access to the internet, who you have to just try and sidestep.
