Baiting needs to be defined in a clear and objective manner. Otherwise anything could be considered baiting.
Rule 7 (Flamebaiting and Trolling) explains it a bit, but not everything is considered baiting (the note actually gives it away when it states 'baiting users into a fight'). There are clear cases of it and mods generally know how to decipher what is/isn't it.
- Lying to prove a point
- Hit-and-run posting (posting in a thread just to rile people up)
- History of attacking a brand/company/fans of said brand/company
