I think they don’t tend to post in game related topics for a reason however you could also argue that favourite zone/pet/mount type threads are actually game related. The ones they’ll never post in are the X is bad because of Y or we need Z in the game type posts.
Arguably Boots appreciation thread - #44 by Tyrskorn is game related as well as I Finally Found My Class! - #41 by Arythwinn. Blue posts in game related threads but ones that aren’t going to go down in a flame wall as they start with the ubiquitous everyone agrees that such and such is bad for the game etc.
