Where do all these videos of hangings come from?

I know there are about 2000 suicides each day in the world, but I am still wondering where all these videos that feature a hanging are coming from.

Who is uploading them, and how are they getting a hold of them? Does someone offer "upload" services or something for videos?

I am not against live streaming or video taping and uploading if someone wants to CTB that way, but I am curious where the gore sites are getting all their material
