Oh, Smogon recommended Bold on that page since neither of the offensive stats mattered since Mandibuzz didn't typically run Knock Off since it sucked in BW. On the website, they only have the BW analyses which are somewhat outdated. They probably did Bold to minimize the attack as much as possible. When a mon doesn't use any physical moves, I always run 0 IVs and a reducing nature like Timid or Bold since attack stat still factors in to confusion damage and Foul Play. So when Special attackers that have a high Attack stat (like Special Tyranitar or Hydreigon) get confused or hit by FP, it minimizes damage from it.

And no, Dragonite isn't banned. It's one of the most common mons in OU, though. I'm not sure what cartridge meta is like, but heavy importance on hazards and U-turn/Volt Switch are a thing on Showdown and it really hinders Dragonite's effectiveness.
