What gives on eBay regarding shill bots?

I think in the last month or two alone I have had the following happen to me on eBay auctions. I don't bid on much; almost all Transformers, but for me it seems exclusive to Transformers:
- Bidding happens early, I jump in
- Normal bidders leading up to the final hour or so
- All of a sudden I get beat, put another bid in, beat again.
- As the price gets close to what I am willing to pay, the other person bids higher than even some other listings are currently going for Buy It Now
- I look at the bid history and some jackhole with < 5 feedback is now bidding everyone out
- Auction ends, I lose
- A few days later either I get a second chance offer or the item is re-listed. Some have been re-listed 3 or more times
This is on the surface shill bidding, but it's happening on such a large amount of sellers with good feedback that I don't believe it can possibly be the sellers unless everyone has turned into a scumbag all at once. What is up? It's almost too calculated to be a person but rather a bot...but what the hell would anyone get out of this? Unless it's eBay itself. I've reported a few of these items but is everyone else experiencing this?
