I pretty much always book my trips last minute so I'm actually really grateful that people double book & then cancel, especially those that post it on the cancellation thread. For my last trip I booked only a month in advance & we got Chef Mickeys, the Crystal Palace, Garden Grill etc all thanks to people that posted on the cancellation thread. But it took a lot of work, I was checking the board 6-7 times a day. What I don't like are people that make multiple reservations and then don't cancel them. I have lots of friends that have done this & it really frustrates me. Some restaurants that I've walked into are barely full when I show up & and yet its practically impossible to make a reservation there. Unfortunately, I don't think there's any way to stop this from happening.
