There's a game jam open right now that is ending in 1,700 years. Haha. Funny. Right? Haha. Im laughing. /s

In all seriousness, there are a bunch of game jams that have excessive time ranges. 1700 years, 77 years? In my opinion, anything exceeding a year shouldn't be allowed. They hog up a considerable amount of space on the jam page, among many other cons, and they're literally just memes.  Perhaps a filter would be a fair approach? Let us filter out those jams that are exceeding X duration? 

Thank you for all you do :)
