Some dude is going to deactivate his spam protection (Akismet) for one day, on December 15th, and the idea is actually starting to spread.
What a pointless idea… I mean, everyone knows how many spam they're getting each day: Akismet as a WordPress plugin comes with a spam counter. I know I get between 100 and 300 spams every single day, how cool would it be that on this particular day I deactivate my comment condom and manually moderate this many comments? You said it, completely uncool.
The interesting part — there is one after all — of this experiment is, if the idea really gains momentum, we'll see how the spam count increases this particular day: just like everyday, or will spammers put an extra effort in their work?
