probably not a random wold kidnap you after 2-3 hours if you didn't move... think about it standing in 1 spot for the whole time? being in battle doesnt always keep you online it helps but only if rs doesnt notice yo and send you a problem... they can shoot you a random event on purpose every hour... they can pop a mod on over to talk to you and if you dont answer a mod... your in trouble:P remember that afk training is against jagex rules and can get you banned
