Best practices for hiding your multiboxing in World of Warcraft (and Classic WoW).
- Rename Levelbuddy's executable.
- Do not jump.
Do not use it because it's the well known multibox behaviour.
- Enable "Alt-Tab Imitation" feature.
At least, when you are not alone.
- Do not multibox in public.
Also, I recommend you to stop multiboxing for a while (like a month).
