Yes I understand that. It's fully understand that it's not appropriate that a thumbnail from a porn video is shown while at work - but who is marking the video? I don't see anywhere on DTube where the users can mark content as NSFW, so it's a moderator somewhere! Also I don't understand why this thumbnail is market as NSFW when we are exposed to Satanism all the time anyway - but btw this actually irrelevant. I am just curious who marks peoples videos as NSFW.
