We don't post on our play accounts. If I want to give feedback to the developers about my play experience, I do the same thing I do when I'm compiling player feedback from the forums. I email them directly. And I wouldn't dare troll these forums and create more work for our moderators. ;)
But yes, we do play on normal acheter wow gold accounts with standard character names. I've been playing five different characters since patch 4.0.3a launched, some on PvP realms and some on PvE realms.
Low-level: troll hunter, worgen druid, goblin shaman
80+: gnome warlock, undead death knight
