I have heard from some mods that we already have video limits, such as sub 20 mins in 8 star or sub 55 mins in 50 star I believe. I think increasing the limit would actually make the game less popular since it is really hard to record. Many don't have it on Wii U Vc, and capture cards can be hard to find. It took me awhile to get my setup going, and it's hard to get good video, so I understand when people would prefer not to record.
Beat Bowser in the Dark World, Beat Bowser in the Fire Sea, and most IL runs don't have video evidence.
Because they're not taken as seriously. If there's a specific run you think is impossible then contact the runner and ask them how they did it, or report it if you really have to.
Really_tall and J_dude kinda summed this up perfectly, but just to add 1 extra thing, if you think a certain run needs reviewing probably the best place to report it is the discord (which you can find in the resources tab).
