It sadly doesnt happen often, but sometimes...

I believe the term is "Naming and Shaming" not "Naming or Shaming". If you name someone to shame them, that's definitely not good. But if you name someone to say something good about them, why would that be disallowed?

It's kind of a culture thing. in Japan, people often don't like their name revealed even if it's a good thing because you can be ostracized fore being too (insert positive quality here).
Thus, while not REALLY a problem on the English forums, it's generally a problem to name drop even if it's positive.
Of course it's moot if you get the person's permission, but the mods may still delete it.
