I've been trying to clear an arkan history for one of the player that got detected with arkan 80% no recoil from my server. He is legit with handcam proof. Is there a way to clear his arkan history from io.serverarmour?

Arkan data does not get purged. If I start doing that, it would just create bias. Arkan violation does not mean someone is a cheater, it's just information to help aid a admin WHEN and only WHEN they suspected someone is suspicious, it should never be the only reason to ban anyone. 

I myself have gotten an arkan as a server owner just because I'm good with the M2 which has an easy spray to being with. Especially now that everyone is getting pinged with the new recoils, it would be useful to either have a new set of data or a way to filter out all these false pings
