I am telling you what Blizzard’s rules are and why they exist. From there you can determine if you want to take the risk or not.
Nobody here can pass judgement on what you want - we can only make sure you know the risks, and that you can decide if they apply to you or not.
THIS is why multiboxing was brought up. That is the ruleset that applies and would possibly cause you issues.
Multiboxing, or playing multiple World of Warcraft accounts at once, is not a violation of our End User License Agreement. Please note, however, that use of all software or hardware mechanisms used to mirror commands to multiple World of Warcraft accounts at the same time, or to automate or streamline multiboxing in any way may result in account penalties.
