We need tighter restrictions on account creation to prevent (or at least slow) the mass creation of accounts. This would include mandatory email verification and limiting of email domains that you can use.
I would like better trade restrictions for new accounts. This is something that I'm currently planning but I'd like to find a good balance so that we don't put off new legitimate players.
Ideally we would also get a lot of improvements to the tools that are required to combat the hand played gold farmers, as the current ones weren't designed with that in mind and simply aren't up to the task.
