Bidding on your own names at NameJet…?

Once in awhile I see people bidding on their own domains at NJ. I would think it would be frowned upon.

Today's seems more obvious than normal. Or am I missing something here?

Airlinejobs.com owned by Andy Booth at Booth.com and high bidder is BQDNcom (James Booth).

3 bids down we see Boothcom as a bidder.

Same thing with MovieZone.com. Owned by Andy Booth in which he currently appears to be the high bidder.

High Bid: $2,475 USD by boothcom

They actually won their own domain…
