For what it's worth, the increase in staff members seems completely as if it were a precaution. While no, I don't see the forum doubling by any means, a 50% increase would probably warrant two additional staff members, and simply having names they can recognize can't hurt.
I imagine that if the demotion of Metal Arc had not come, Wist may have not been appointed and these two may have instead. But that's neither here nor there.
While no, I don't think it will be needed in the long run, sometimes you can't just let shit happen.
You also have to consider the potential for people who don't like FESS and are petty enough to harass it's once population when the news fully spreads.
