As a female attendee of Pycon this year I was overwhelmed by all the friendly people I met. Now maybe my sense of humor is juvenile or coarse but what was overheard is a joke I'd probably make myself.
Keep in mind Pycon was attended by plenty of minors so making adult themed jokes in a crowded room was really not the smartest move. Regardless it clearly states in the Code of Conduct (https://us.pycon.org/2012/codeofconduct/) that the correct action is to find a staff member and report it and NOT post someones picture on twitter attached to hearsay.
If the comments were directed at OP that's a different story but that doesn't seem to be the case. When I go back to Pycon next year I don't want to be treated differently and as a sound minded adult I certainly don't need people to censor themselves around me.
