ttps://www.bungie.net/en/Clan/Detail/697802 Here is the link you can join the group then you need to make the group your clan and after you'll get "Devious" under your gamertag in game which will let you know your in the clan and group. I unfortunately can't end invites to the clan as bungie doesn't have that available yet.

I think the link is broken, doesn't take me anywhere

You can search for the clan. Just type Devious in the search bar. It'll take you to the same place. I'll check up in the link
