The trouble is the same one that has plagued the Internet since the era of bulletin boards, usenet, chatrooms and the like. Being behind a screen people can say and act in ways they likely wouldn't in real life. Without repercussion, people can and will go to extremes in ways that are unfathomable. It is fine to discuss and debate, to have an opinion and argue a case civilly, but name calling, death/assault threats, releasing RL addresses/phone numbers, suggesting suicide and circulating intimate photographs are completely beyond the line.
The Zoë case is the current topic du jours and in fairness is relevant to a gaming community. Whatever people's opinions, views or even the facts, it has undoubtedly cast a shadow of disrepute among many journalists and developers. It raises the question of how much of what news/reviews sites say can be trusted. Consider further issues such as press embargoes, bullshots, scripted demos, Jeff Gerstmann/Gamespot, Lauren Wainwright, all the other scandals as well as the issues with Greenlight and Indie development in general. It all adds up to a sad state of affairs for game's journalism.
Cynics might say it's par for the course and the same in every industry. Apologists might tut and say the ex shouldn't be airing dirty laundry in public. Whatever people say, the games industry does suffer for this stuff. And there are conversations to be had about these things, awareness of sites and people to avoid and judgement to be reserved. Marketing and PR you expect bullshit from because it's their job to make gamers believe their game is good when it might not be. But journalists are supposed to be on our side; if they prefer to be in bed, literally or figuratively, with a developer or manufacturer, then they aren't a journalist any more, they're a marketing dept.
