Having an addon that will automatically accept any queue pop of LFR and LFD??
So for instance you are afk, in the bathroom, making a sandwich, picking up your daughter from soccer practice, doing laundry, or any other number of things, you will always accept and get in to any LFR / LFD you queue up for.
I couldn't find anything in the TOS that would indicate that an addon like this would be illegal.
