Well if the newbies are smart enough to be reading this thread, then one would think that they would be smart enough to look at the trade forums to look up the cost of the rares.
This would only be the case if said newbies actually had an idea of what the rares are worth in the first place. If they don't then they will happily take 30k as to get started on a mage character or whatever.
If all the rares locations went public, then after awhile the prices will drop.
The more people looking for the rares, the more common the knowledge of the spawn timers.
Everyone who has ever played UO knows that rares = Money...
