Considering you’ve only made one project, and you’ve submitted it to multiple game jams, there’s a chance you were banned from posting to Game Jams. Considering your account and project were both made 1 day ago, how many game jams did you post your project in?
In either case, you can contact support for more details.
Posting one project to multiple game jams is allowed, but the project has to fit all of the game jams themes. If it doesn’t it can be seen as spamming.
