If someone was willing to devote 8 hours to looking around P&S, I bet they could report 1000 posts and probably have a decent hit rate at that.  It would just take some time--the garbage is there; it just needs to be moved to the dumpster.  Having said that, I'm not certain Theymos even wants that or any other section emptied of content altogether.

I say that because of how Bitcoin Discussion is.  I'm pretty sure Hilariousandco would trashcan many posts in that section, but he doesn't, and I suspect that has more to do with what Theymos wants than what hilariousandco wants.  I don't know what the highest # of posts I've reported in a day, but it's probably close to 100--and that's in my spare time, without getting paid or even wanting to be a moderator.  1000 would be no problem to send to the can, IF you were allowed to.
