There are so many things wrong with the PyCon incident surrounding Adria Richards and the ensuing fall-out that the specific behaviour of the people involved doesn’t even begin to get into it.
The events, as I understand it, are thus: Adria Richards was in conversation with two men at a coding conference, during a presentation. The conversation moved on–or maybe it didn’t, it’s unclear–and the two men cracked some jokes that were sexual in nature. Richards took a photo of the men, and tweeted about her issue with the jokes. PyCon organizers saw the tweet, came into the presentation to speak to the men in private. The men apologized, and did not return to the presentation. Richards wrote a blog post about her experience. The internet explodes in hate, as it is wont to do, with rape threats, death threats, and public and private harassment directed at both Richards and PyCon developers.
Then, Playhaven, the employer of one of the men, decides to fire him. Richards’ website is targeted by a DDOS attack, then Richards’ employer, SendGrid, also falls victim. So SendGrid fires Richards.
In short: it’s a mess.
