DashCon
DashCon (originally titled Tumbl-Con USA) was a fan convention catering primarily to users of the blogging platform Tumblr, with a particular emphasis on fandoms. Held over the weekend of July 11, 2014, at the Renaissance Schaumburg Convention Center Hotel in Schaumburg, Illinois, the inaugural convention quickly became infamous for allegations of mismanagement and corruption among organizers, an alleged abrupt demand by the hotel for an upfront payment of cash for use of its facilities, and celebrity guests being forced to drop out of the convention after they were informed by the hotel that they would be responsible for paying for their rooms.
