I own a small apparel company that operates an e-commerce shop. Our target demographic is young adults, and as such our brand and marketing material features an edgy and cool style. A lot of our material features various kinds of stunts, e.g. motorcycle tricks, backflips, freeclimbing, etc. We also have a section of our site where people can submit videos, and each week we choose to feature someone's video. These videos can be anything and don't have to include any kinds of stunts. However, I've had several people warn me that if a kid severely injures himself or dies while trying to make a video or get a cool picture to post on social media, our company could be held liable. To what extent is this valid concern? Is this something that is a common issue, and if so, what are the usual results?
