GAC Data collection tools should be stopped.

I may be wrong, but it sounds like their current development is focused on a GAC match history. I don’t see any issue with recording information that was available at one time - it only becomes a problem if this database is capable of sharing information from matches the player didn’t participate in.

Record my matches and give recommendations, sure. But if any third party gives me information that I should have no way of knowing (like my opponent’s match history, attack and defense tendencies, so on) that would pretty much be cheating.
