Be your own spam filter

[Haroenv]

The game would be in three steps: marking, learning and testing.

1. The first step is to mark as fast as possible things as spam or not spam (fake emails for example)
2. The second step is to write some heuristics engine (maybe based on content, sender etc.) to mark things as spam
3. Then finally your algorithm will get tested for efficiency and you get a final score with leaderboard etc.
