Surely not a web site worth of information. Though many would be glad to take a bump in exchange for $$/free flights, I really can not see that many spending time trying to find a flight that seems to have a chance of bumping. In fact, any flight that was a regular for bumping would in time fall off the list as the airlines track these and would reduce the overbooking factor on that flight.

So, he here is the proposed scenario. I need to go from ATL-BOS on 21 June. I WANT to get bumped. I check the site. One guy once got bumped on late flight. Even though I want to get there in the early evening, I book the late one. I get to airport. There are 30 empty seats. ****. Stupid web site.
