These nuage centers have a rotating cast of "presenters." They try really hard to get legit (or formerly-legit) people to sell out, so they can put at least one "respected" person on the bill with their crew of pretendians. Usually they do this by misrepresenting themselves and their group, pressuring Natives to sign contracts before they've had a chance to look too closely at what they're signing up for. They claim it will be a forum for traditional or interfaith discussion, then they find out they're in bed with a bunch of pretendian ceremony-sellers. Then even if the swindled person backs out, or never goes back, they will continue to use their photo and name to promote their center.
There are people I know personally - both Native and non - who have been approached by their staff for this nasty purpose. They use Facebook and other social media to try to find people they can exploit, or bribe into exploiting their culture.
