I'm not saying anything conclusively here except somebody neglected to do any due diligence. A search on Github would have revealed the project name already existed.
edit: The domain name was registered on March 9, 2017 -- four days after my project was posted to one of Facebook's open source repositories.
If anybody has any information on who I can contact about this I would greatly appreciate it.
Were you by chance on this project, or know of how I can get in touch with somebody who oversees things like this?
