I disagree. Flights listed on bumptracker.com are more likely to attract people who are less likely to no-show than the average airline passenger, so an airline would be wise to mine the data and cut back overbooking on those flights.
Not a big deal, though, as the amount of data on bumptracker.com is very, very small, relatively speaking, and the number of seats the airline should reduce from inventory is probably no more than 1, given that not many people are actively trying to book on bumpable flights.
In theory, though, we should try the fake-out method to maintain the upper hand.
