I honestly hated the thing at first. In all fairness, however, I hate most things...and I always hate change.
That being said, I haven't had any issues with it staying put, and I just close it on each of my characters after the conquest resets. As far as the "forced advertising"...it's no worse than the Cartel Market button at the top of the screen. It's there, it's not in the way, so just ignore it.
If it was always open and couldn't be closed, moved or deleted...yeah, different story. With all the things I'd like them to focus on, this bar is very near the bottom of the list.
We need a name purge, and we need guild caps either significantly either, or removed altogether. That's just my opinion.
