It's a terrible decision on the account owners side and really in no way relates to trading, I've never trusted people with any form of account info for any medium even family.Currently some number of players "trade" by sharing passwords (I want to use X and you want to use Y lets swap accounts to try them out). Actual in game trading or not the issue of scamming exists. I am not involved in that, but I know of people who have and who have as a result had their stuff trashed.
