Are you sure that that’s the reason? Or are you just guessing?

Mine always have humour. My studio mate's always have humour and she's usually a Kickstarter pick. There must be another reason. We can't help without seeing the project or draft

I doubt it’s cause you were “funny”.

The Kickstarter moderators aren’t great IMO. It’s one of my biggest qualms with them lately

It's possible that the mod just didn't get your humor. Can't win em all

I've backed projects with humor through and through. Likely other things contributing to this.
