I sent a ticket request and got back the following response yesterday.
Nice to see they actually read and respond back in a constructive manner.

I was having issues logging and once I received this all was well in the world.
Back to my regularly scheduled MB'ing.

I currently multibox 5 accounts at once and the new patch that has introduced the antibotting measures is apparently affect multiboxers inadvertently.

Is there a way to flag my 5 accounts as multiboxing and not botting?
