Hi there, our official stance on all those matters can be found in our terms of use. The only exception might be gold farming which, if is not done using automation and is not done with the intent of selling on for real world currency, we have no problem with. There is the possibility that the terms of use could be amended at any time if people find caveats that we haven't expressly covered.
Here's a few passages from our terms of use that may be of interest for your article.

Real World Trading
You may not advertise the intent to or commit the act of buying (excluding direct purchases from Hunted Cow Studios Ltd), selling, trading, sharing, or transferring access to any game account, game points or any other commodities within the game for money, money's worth or commodities out with the game. Game accounts are non-transferrable under any circumstances. All game accounts, characters, items, game points, and other commodities within the game are the sole property of Hunted Cow Studios Ltd. The selling for money or trading of any these items is a breach of this Agreement.
Uploading Material to Our Sites
Use of any form of automation or 3rd party scripts on our Sites, without prior permission from Hunted Cow Studios Ltd, will result in your account being terminated.
Game Bugs and Cheats
Game bugs should be reported directly via our support centre (
http://support.huntedcow.com). You may, however, also post bugs in the Bugs Forum in order to ascertain whether what you experienced is, in fact, a bug.
Bugs which are a potential exploit to the game should not be posted publicly. They should be brought to the immediate attention of Hunted Cow Studios Ltd via our support centre (
http://support.huntedcow.com).
You must not knowingly exploit any such bugs or cheats. Doing so puts you in breach of this Agreement and may result in termination of your account.
