My take on this is that it's fine when done properly, meaning the owner of the cache isn't running around collecting all the nearby bugs just to go place them in his/her own cache. For awhile, many people wouldn't drop TB's in this area because of it. And in the few instances that they would drop them off around here, they wouldn't log the TB on the site until someone stumbled upon it & sent an e-mail to the last TB holder. Since the mass of them were rescued, including one of mine, this cache has tamed down. A few of us went out & located it and we each dropped off a TB or 2 that was in our possession.
If you start one, you should at least "eat what you cook" by starting it with your own TB's. People will take/place TB's in the prison if you set the tone of the cache & not be an a** about it.
