Is there ever going to be a multibox limit?

Legit serious question multi boxing is not against the rules but are you guys ever going to add a limit https://www.youtube.com/watch?v=wul3O0Ipmv8 so people can't do that and take over a city by multi boxing with like 10 or more healer accounts was like 10 high gear druids was pretty much unkillable to most horde people was trying to start a raid group just to kill the guy. But will there be a limit eventually so people can't abuse multibox system to become a god pretty much and ruin server?
