With exceptions to auto-cast and auto-attack, both which, are integral and sponsored by game. They are not botting as they have timer limitations and cannot be carelessly left. It is not against the rules to be non-responsive when you are logged in your character, and being non-responsive during auto-cast/attack is not illegal, as they would expire itself but if you are resuming auto-attack/casting even after expiration occur and deem non-responsive in between two periods, then otherwise you would be botting.
