What is with all these old threads revisited?

Ever since the Mayweather Mosley fight, I keep clicking on threads that end up being a few months old, some even a few years old. And they all have to do with Mayweather, Mosley, and even Pacquiao for some reason. I understand being happy your fighter won, but going through all the trouble to dig up old threads just to prove your point is beyond pathetic. I am trying to see some new threads/opinions from fellow fans, but always end up clicking on shit from last year or even 2007. How the hell do even remember what you posted that long ago? I swear some posters on here are so hung up on debates they had three years ago and now they are so stoked that they can finally prove their point.
