This is one of the things that makes me prefer HC to HF.  Modding and being called out is very public and transparent.  There is very little going on behind the scenes. 
 
It's OK to call people out (when they should be called out) as long as it's done in a relatively civil manner.  Al did that in the HC thread.  Nobody has to feel that a friend has betrayed them because that rarely happens.  Of course, people that can't take being called out don't last long here.  That's because eventually everybody posts something stupid and get's called on it.
