Some of the "regulars" in collectables who trade frequently seem to think they can do whatever they want, and frequently, they do whatever they want, even when this means harming others.
Quickseller, you're a moron. First off, look at your trust score..how can anyone take you seriously? Sure, I am always going to be known as the guy who plagiarized a couple posts one single day (not tons of posts like you incorrectly stated once), which didn't even benefit me what so ever. But, at least I'm a somewhat respected member here, unlike yourself.
I know the collectibles sub way better than you do, and you're wrong. First, I know the first and last name to MANY of the people there. So no, we don't all stay anonymous. Secondly, regulars don't just think they can do whatever they want. There are many members (like TeeGumes for ex.) who will call anyone out for any sort of shenanigans.
I take this stuff seriously, and there is ONE person that I believe is shill bidding often atm..and I can't prove that. So I simply don't bid on their items. So how does yourself or OP know this to be certain? I can't speak for OP, but I know you just like to hear (or see) yourself talk. Even if it's babbling nonsense.
Edit: Also, and more so for OP, you need to realize how collectible markets work for any kind of collectible. We will often bid in auctions having no intention of actually wining the item. That is because we are more than willing to buy the items at the low price, but knowing that we are highly unlikely to have the winning bid because the items "market" tends to be set around a certain price range. This is the same on ebay, auction houses, or whatever for many types of collectibles whether it be baseball cards or artwork. This doesn't mean we are trying to inflate the price so newbies have to pay more, it's simply getting the auction off and going (often at least getting the price up to it's original cost) if we happen to win, while not expecting to...it's a bonus! I won a lot the other day I had no faith in winning but was pleasantly surprised! There is nothing wrong w/any of this. Maybe this is not what you meant by your post, but sure seems like it.
