Yes, there is no voting, and no rating. It's how 7dfps works: Submissions remain open indefinitely, and the easiest way to do that is set the date into the future. https://twitter.com/7dfps/status/1338392213735149568
But in the description of this Jam it literally:
when is 7dfps?
7dfps 2020 is December 4 - 13 in your local time.
Maybe you can change the description to "If you happen to make an FPS game and upload it to itch.io, add it to this list of other fps games where it won't get votes or ratings.."
