No, and I agree...this would be another consideration as well as mentioned in my post previous to this one.
It is also something that would have to be maintained on the Order shard - though I would like to see those comments I've seen posted about Order being 'Very strict when it comes to RP" - which is something I have never experienced once since joining order about a year after the merger. I've seen people 'wrist-slapped' (by other players and quite politely) for veering away too much or for an extended period of time, but never for NOT RPing.
The only bad experience I had was just before joining the Bane of the Aegis - when I was kicked out of a guild because I wasn't logged in often enough (apparently 4-6 hours a day wasn't enough - go figure) - tame compared to some of the things I encountered in WoW.
And in the cases I've seen you describe above...when something like that has come up, which usually happens in Market Place when things are slow or a comment is made...you know how conversations tangent...the speakers take it to a private room.
