Don't know don't care. Crafting/Gathering leveing in this game is an overkill. A few people like it (very few) but the remaining detest it.

I really don't see that big of a deal and most people just minimize the game and keep hitting the controller button.

And NO you cant tell if the guys is botting by simply talking to them. There could be many reasons they didn't respond (not in the mood, didn't pay attention, mindlessly pressing buttons while watching a movie....etc). If they are not using a tool to access game data then this I don't care and neither should you.
