This is the thread about bots and their detection status:
Unsicherer/Detected
MMO Mimic
Blizzard detected Mimic a few times in the past and the creators lied about its security status. If you use a bot, don't use Mimic or WoW Gremlin.
Use Pirox PvPTool ( it can do more then pvp) or another bot in the list
If you have Pirox Elite, you can bot as many clients, as your hardware can handle
