I see no problem in learning, we are all here to do that. What I don't like to see is someone who always posts links to auctions. Some people put in good amounts of time pruning thru auctions, hoping to get a good deal. I see it as their reward for research. And maybe, just maybe, they squeak one thru when no one is looking. Again, good on them.
But it's all for nothing when there is a place where someone can see postings to all the good auctions. Why would there be any incentive to do your own work and looking for things?
If you want to share something about a gun or piece of militaria, why not post a picture of what you see and leave the auction anonymous? We can still learn that way. Expired auctions and even current auctions with pics copied over, no direct links are posted about very often. Many with questions about why for the price? Something special? General questions about an item? Specific questions about an item? The point still gets across and the learning still takes place.
A long time ago, auctions were allowed here, but in much less frequency and it was meant to drive home a specific point. Something that was felt to be a very good lesson on something. Now, it just seems to be that auctions get posted as, Hey check out this one! Where is the lesson? Where is the question?
This has been something that has bothered me for some time. I've even sent a note to Dutch about this. I just feel that I need to speak my peace about it.
