This Isn't Allowed, Right?

I recently saw a video popped up at my YT homepage, wich is a video showing 4 of the hidden relics. I warned him that he might have to take this and his other videos down, but as I do not fully know the rules, maybe you can take a look at it. The link:
PS: If I have to remove the thread because of the link, I'll immediatly do that :)

 

yep, it isn't allowed to reveal the location of hidden relics

 

RIP for the dude that made that

 

Technically, it isn't allowed here, on the forums, the wiki or ingame. There's no way to remove the video from youtube since we got like no authority over the poster there. Now there are people who want to do it easily, so they can search it on google easily and follow a guide or those who rather enjoy an adventure. Anyhow, this isn't the only video on YT that shows the relic locations.

 

I was under the impression that it's ok to reveal them in other places, just not on the forums or wiki.
