There's nothing wrong with
some of the lp-vids, however most of the uploaders epicfail.
By failing, I mean: uploading a footage that might worth something if the uploader would bother to at least mention the title of the demo actually played (or god forgive, a link to it), but almost all of them just advertise themselves and their unrelated other yt channels and vids.
Also the kids who do nothing but yell "holy shit" in the microphone all time (even if a cute manga-style girl appeared in a not-even-surprising manner, they scream like lucifer himself have spawned there in real life.
I've watched a lot of these videos, and I can tell you with confidence, videos that get downrated are usually just that bad.
I don't know much about reddit but in fairness, who cares? It's nothing new from a trolling hub.
Oh, sorry, it's officially called social hub.
Generally, if your video meets a few (obvious) demands, I don't think it'd be downrated.
-a proper narration in cases where the random fella would just scream like a 8yr old girl in the horror house
-information about the demo itself (proper name, how one can access it)
-explanation of the appearing bugs/glitches if any (there are, in most cases)
-at least some hints about how powerful rig you need for a decent experience
-mostly nobody cares how a kid's face looks like with the oculus on so that part should not take more than 15% of screen space
There are plenty GTA V videos and many more related to other games, but barely any of them actually goes into details like injector being used (vorpx/vireio/mod), no hints on other tweaks like fov hack used for showcased video, and they mostly miss the fact that their attempt failed in finding optimal settings, and not even the uploader experienced the game in the way claimed from the video's description.
These kinds of "Look man, got zah oculus, watch mah uber gameplay wiz GTA5 and be jelly" videos simply suck.
As an idea, it might be the makers of the crappy videos that downrate all the others for some random childish reason.
Example of very bad footage:
