in my experience;
on one rustez server a player asked as they waited for brad and he wasn't there, they'd do barrels etc. they were told by admin they could wait around 10mins, but if brad was 25+mins off, they'd be better off coming back later to try again. i asked if it was camping to wait around (looking for some clarification, so i don't get in trouble ) and an admin said that people should be considerate of others. love it, but i see what you did there
on another rustez server, a player waited the full reset time for brad (informing in chat to everyone that they are doing so, they missed out on doing brad as they said they went afk for a sec and they then said they'd wait another full reset.) Community told them that was camping, Admin quoted the camping rules from the site, everyone reading chat understood that to mean it wasn't camping because they hadn't logged off, they could wait around for brad.
