I saw this tweet which, according to Google Translate, reads as follows:
Thibaut Assus, one of the creators of ParisRB, was tried at the Paris Assizes and found guilty of rape and sexual assault with the aggravating circumstance: abuse of the authority conferred on him by his functions.
He was sentenced to 5 years in prison at first instance.
If you have been a victim or witness to certain acts or behaviors following a RailsGirls event, at ParisRB or in any other context, whether it seems more or less serious to you, do not hesitate to contact the organizers of the association here.
Such acts are very serious, in a community advocating benevolence like ParisRB. Women On Rails conveys its full support to the victims. We believe you and we are here for you.
The Women On Rails organizers.
It is truly sickening news. I have not been able to get additional details yet, but I want to fill people in on what I know right now.
This person independently created/organized Elm Europe, inviting a lot of speakers from the Elm community. I feel sick having spoken at this event, and I pray to god that everyone who attended was safe.
I have reached out to people from Women on Rails and Elm Paris to try to find out more details. It seems to have been a jury trial, but when does the 5 year sentence begin? Will it be possible for him to try to organize more events before that? Anything that might help us act to protect people as quickly as possible.
I have also contacted the ESF lawyer to learn what can be done to make sure independently organized events are safe. E.g. Can we ensure that the name “Elm” is not used by certain events? If so, how does that work internationally? What do other open source projects do? How can speakers do background checks on organizers? Etc.
That is all I know right now. Thank you to @Warry for bringing this to the attention of non-French speakers here, and I want to reiterate what WomenOnRails, ElmBridge and elm-conf have said. Specifically emphasizing that “If you have been a victim or witness to certain acts or behaviors […] whether it seems more or less serious to you, do not hesitate to contact the organizers of the association here.” And as a speaker, I now understand that knowing that a conference has a Code of Conduct is not sufficient. I need to be asking a lot of questions about the specific staff and safety procedures at a conference. “If someone reports they feel uncomfortable around someone else, what happens next? Are there minders? Who are they? What is the protocol on ejection? Etc.” I encourage other speakers to do the same, and to decline to attend if they are not getting good answers.
[Edit: Having speakers ask these questions obviously cannot guarantee that the event will be safe, but it seems like a responsible precaution, especially if your talk may be a draw for the conference. There is further discussion/refinement below!]
