What we, the staff, are 100% against is anything that is actually against the law in an obvious way, such as fraudulent activities involving PayPal/Western Union/etc, credit card theft, identity theft, fake IDs, shop-lifting.. those kinds of things.
What we will allow are the usual virtual or in-game scams, such as scams or cons for virtual currency, account scams (as long as it is strictly an account scam), cd-key scams (to an extent) and other things of that sort.
However, you may keep in mind that MMOwned does not support any scamming whatsoever. The only reasons we have the WoW Scams section (notice, it says WoW Scams) around is so that we can further educate you members about how to protect yourself from such scams.
