I'm not the creator or a moderator of this community or anything but I'm the only one posting. I'm going to try to post a bunch of the videos I've saved over the years (I've got hundreds lol) to get the ball rolling.
It seems like the best way to share videos here is to upload them to your preferred website and put the link in your post. I've been using Imgur because you don't need an account to upload. You do have to use the desktop site if you want to upload from mobile without the app.
I get where you're coming from but it makes sense to have equivalents for some of them. Like in this case, people are going to want a place to share and watch crazy/shocking videos.
