This makes me laugh, especially since it got 23 upvotes.
People using pvp or fishing bots pay a sub.
People that exploit bugs pay a sub.
Groups that sell carries for real money pay a sub.
Blizzard will ban these guys and lose thousands of dollars in subs but they won’t ban multiboxers, which are probably less than 1% of WoW’s population, because “$$$.”
Much sense, very logic 
How about they don’t ban multiboxers because the software they use isn’t a bot program and having more than one account isn’t a crime.
