Disco Crews' Perks pages and opting out

Every Disco Crew has a Perks page with deals for its members. It shows offers from the Crew's own sponsors and paid promotions, each clearly labeled.

• Disco Crews are in by default. An organizer can turn business perks off at any time.
• A Disco Crew's blocked categories always apply.
• At most 5 paid perks show on a Disco Crew's Perks page at once, so it never turns into an ad feed.
• A Disco Crew that's off, full or blocks your category shows as unavailable when you pick Crews, with the reason.
