Scam

Scams occur when one player or a group of players deceive other players out of money, goods, or enjoyment in-game. The only way to fall victim to a scam is to be unaware of them; knowledge and a little common sense will protect you from any scam another player tries.

Identifying a scam
In general, any offer that appears to be too good to be true is probably a scam. If you are in doubt as to whether a deal is genuine, ask on a public channel. And, if you catch a scammer in the act, be sure to let everyone around you know what he's up to and report it to Arenanet as soon as possible.

Be cautious about paying any fee in advance of any service (e.g. runs) and always double check trade windows before accepting any deals, there is nothing people won't try, similar looking objects (such as mursaat tokens and ectoplasm), weapons that are only slightly different to what is advertised (sundering 19% instead of 20), and most commonly simply displaying incorrect but misleading sums of money (6 gold instead of 6 platinum).

People are not afraid to impersonate moderators or falsely claim that you owe them money for a previous service and will even ironically threaten you with action against your account.

Reporting a scam or policy violation

 * 1) Generate proof of the scam. The PlayNC support site recommends that you include the following information about the scam:

 * 4) The area in which the scam took place.
 * 5) The time of the scam, including your time zone.

Note
In certain cases, ArenaNet will not take any action for petty scams for example, say if someone took 500 gold from you but didn't finish your run or the selling of a common quest item such as "Althea's Ashes". This is due to the large number of cases they have to deal with and the more serious violations are their priority.
