They are spammy videos with a spammy description filled with download/affiliate links. They have no related videos on the right hand side. No videos whats so ever related to their title or description. Just popular videos like popular vloggers etc that are there by default. Im guessing they some how trick the system into thinking their video has no title/description so no related videos pops up? If anyone knows how or has any information about it please reply! Thanks!
