I think this would be 95% cool and maybe 5% useful too.
I think there should be a place to read the summoner's code in-client.
Maybe even prompt people to read specific stuff based on reports they are receiving. Not for severe offences obviously, and not instead of punishment or shortly before it (so it's not exploitable) but maybe when someone reaches half way from 100% good behaviour to 50% towards the first chat ban a small pop-up indicating what to check out. Or maybe when someone gets an unusually high amount of reports in a small span (we are still talking small numbers, not enough for a punishment but when a couple valid reports are close to eachother) to scare them straight a little.
What do you all think?
P.S. I for one would like to also have a place in client with all the LoL lore, but I guess that wouldn't be too interesting to most.
