It is also much easier to find spam (f.e. in almost every megathread) than create alt to post spam to report it.
If you were to run this competition, you would need to limit which boards reports can come from, but again, you are depending on theymos to give you those data. The reason I say this is because anyone can go in to a random ANN thread on the altcoin boards and rack up hundreds of reports an hour just from the usual "Great project" and "To the moon" type posts. Doing so doesn't really help to clean up the forum, because no one with any sanity is visiting those threads anyway.
Or only Theymos has it?
