I've watched a few horror stories. but they're all pretty much after a while same cut and paste formula which makes it so.. the thing is no longer scary.
one horror movie I watched (made and produced/shown via youtube, that was not the same trope though, but likewise, wasn't even scary.. That horror movie of course is something known as "Marble hornets (which also happens to be the uploaders chosen SN)
For the heck of it, I feel you would enjoy such a laughing stock of this horrendously made movie. so here is
the link. Mind you, they do some crazy graphical and sound interference in their post production. But for being a 'out of pocket/profitless movie" that they did it makes it actually rather amazing.
it is suggested to watch the replies to them from another uploader known as "totheark" but I didn't and I still got the storyline, what little there was. and still found the thing not at all scary, but with a decent amount of suspense if you hold off your disbelief.
