I added a rule to not use wall/pm/blog posts.
Someone could easily brand themselves as "helpful" and then provide examples from those places helping a friend. This is about being true to yourself, what's your brand and give examples.
An example for me, I would consider my brand to be "Friend". It's simple, but it's me. I'll talk and be friendly to everyone, I'm a fan of all so I can talk with anyone about their artists if I have heard them. I'm everybody's buddy who happens to be a mod and tries to get people to follow the rules.
