Well, it sounds dishonest and not in the spirit of Ebay and therefore certainly not something I would ever consider under any circumstances whatsoever. It saddens me that there are people who do such things.
If you do as pdlouche says and just get someone to put a bid in at your minimum comfortable sale price then it's exactly the same as setting a reserve. It's only as immoral as putting a reserve, it just means eBay don't get the extra dough and I'm absolutely ok with that.
