This isn't going to happen. Staff are already swamped and I think it should be left up to the community to police just like scams are. Merit abuse is probably just going to cause more hassle than it's worth and sadly farmers and "friends" are just trading it or swapping it between themselves and it's regular users who are left feeling the pinch whilst those with a lot of accounts and/or "friends" will just continue to bend the rules to their advantage.
