5-box leveling, balancing efficiency and "safety" ?

[MiRai]

I've read numerous reports from boxers who got banned while doing nothing bad, and had to spend days getting the bans overturned.

Where have you read these reports? On this site, there are, maybe, five players who've recently reported action taken against their account. Five out of, what must be, something like a thousand multiboxers total—the vast majority of whom have never had a single issue in years of playing multiple characters.

It comes down to... If you act like a bot and others think you look like a bot, then you're going to get reported for botting (or zone disruption if you run enough game clients).

EDIT: I forgot to add this, but Blizzard recently added this entry to their knowledge base:

If you used to cheat on other games, have trainers etc, (before you plan to play wow), may i suggest that you reformat your harddrive and reinstall the OS before you start boxing (warden, the "anti cheat software" gets installed when you install wow, it could detect your "old sins" hehe), if you happen to have some running accidently etc).

Be super critical of everything you install after this, like "software for keyboards" etc, as they can contain automation features, worst case scenario.

Absolutely nothing I've quoted above is true, so please stop spreading this misinformation. You've been warned about this already, and this is your final warning.

You can get some nasty whispers, but dont reply, just ignore them.

I think the better thing to do would be to reply and not be a dick, because if you ignore them then you could easily be viewed as a bot.
