They get closed, Grover, so we can protect our advertisers. Everytime the question comes up, people--often those who've never even tried the stuff--take the opportunity to paint legal bud in a negative light, and as a board supported by advertisers, that's not what we want. So, having learned that this inevitably happens after many dozens of similar threads, we have learned to pre-empt those negative comments by closing the thread as soon as we've provided our blurb of standard information about legal bud.

This doesn't in any way impinge on your freedom to discuss legal bud. You can do that all you want through IM or other means of electronic communication. We just want to promote the product positively here as a courtesy to our generous advertisers, and one of the most effective ways we can do that is by closing those threads before they take a negative turn.
