I think he's more than aware of the issue with spam here and you'd have to be blind or have your head in the sand not to see that. I think he takes it seriously otherwise he wouldn't have created it, but that doesn't mean we can't have a little fun in naming it, which may or may not be an attempt to also acknowledge the ridiculousness of the situation, but I don't think there's anything wrong with a little humour especially on this forum.
I assume there are just too many potential consequences with modifying existing boards? I mean if you're going to be serious about it, why push the serious people into an "Other" subforum so the shitposters can continue to overrun the main boards this forum is known for? Maybe I'm being too critical, I believe it is a positive addition, and maybe the Tower will become what I would hope it to become... but without visibility, it may not get much attention and most will continue to go to the main boards. Is this just accepting defeat on the main boards and providing a place for people to flee?
