I think you misunderstood the question. My fault for not saying it in the best way.
I was asking if I (or anyone else) was ALLOWED to use soundfonts.
The game jam hasn't started yet, submissions will be open once it does (when the timer runs out on the main page).
Also, it's against the rules to develop the game before the submission period, meaning you'll have to start development then. Not to say you waisted time making your game, after all, practice makes perfect.
I remember the incident. You were spamming comment on a guys game page because you wanted mobile controls, and he didn't want to add any. You also tried reporting the guy for bullying, which to be fair, I kinda get. I did see the original thread myself and the guy was definitely ragebaiting you. That being said you did still spam comments asking for mobile controls for his game, even though doesn't have to.
I think it would be possible for this ban from gdev game jams to be overturned if you make it clear that you won't do something like what you did last jam again.
Hope this helps.

You can publish a page for your game on gd.games by going to the games dashboard, and setting a link for the game.
Hopefully that should work.
In order to self promote
I've already rated your game. I also wouldn't recommend begging people to play your game, especially if it's in a topic that has nothing to do with your game.
Also, like I said in the comment I left in your games rating page, please add "Trigger once while true" to all the events that play music or sounds.

There's not much to this game, except a whole lot of burnout.
Hopefully I can update this game with all the stuff I originally wanted to add.
