I think this is not true imo On Ebay, they match up your search text with the pin, as closely as possible, it is a good system. However, recently I saw a grail Stitch pin sell for close to half of what it usually sells for because, and I cannot figure out why, no matter how I searched it, the pin ALWAYS appeared at the very bottom of the list when I searched for the pin, often appearing on Page 3, 4, or 5 depending on how many pins you viewed on one page. The only time I managed to get it on Page 1 was when I searched exactly as the person had mentioned it and then only a handful of pins appeared including that one.
The problem with Ebay that DPF doesn't have is that Ebay doesn't allow bumping so auctions like that get lost at the bottom of the listing and the seller can do nothing about it
I do not see that as "taking advantage of" I actually see that as being a smart tactician. I do this all the time on both Ebay and if I sometimes bid on DPF. The whole concept behind bidding at the last second is because you don't want to give time to anyone else to see your bid, analyze it, and try to match or beat it. I think it is one of the smartest things because if you bid your bid early on, you nearly always get outbid I find, putting it at the end, rarely. That's just what I've found after doing it many times so I continue to do it. While we do do it willingly, it really isn't to cheat you out of your pin, but I do it to cheat the other bidders from seeing my bid
Also, I do enjoy how civilized this conversation has been
