1) It depends what you call afk training
-Botting: yea, not allowed
-Putting something on your key and afking: not allowed
-Putting something on your key and staying at your computer: apparently allowed. Ask rob about it, he was falsely banned when a gm though he was afk, but after the conflict the gm explained that it was false since he wasn't afk.
2) How can you prove he's afk training? He could just be holding down a key
@stevenman76: He mentioned that he tried talking to him, but he did not respond back. That's how most of the gms figure out if you are afk or not. I still wouldn't consider putting items on your keys while not afk to still be legit, but that's my opinion.
