I was thinking that because some people give out free items, to ensure that no one takes too many you should be able to see who purchased something from a trade shop. Maybe you could implement this by looking at the chest and doing like /trade history or something like that. A command similar to how /spawner works. I know that 1232012Gamer recently got looted from tons of items when he was being kind enough to hand them out for free but he doesn't know who took all of them. Also if someone had a donation chest and a donation wall they could check who donated and post their name on the wall. Well that's all, lemme know what you think in the comments below. PCcoolguy100 (aka phr33z) says that the logs could also delete after a week from being made to prevent too much archive space.
