Beware of leaving high bids. : eBay Guides

Ebay have failed to close this loop-hole. Say you leave a bid of £60,  on whatever (Item is currently at  £10), I want to know what you have bid, I bid £600.00 , I can then go to bids and see what you have left,then you remove your bid ,saying it was a mistake,and then leave a bid of £61 or a little higher.......This is a bidding scam,and needs to be stopped,unless you are prepared to SNIPE,many of you,like me will not win much.
