Abusing the Trade feature to interrupt, etc

[Argyle_Darkheart]

Just because I can fix it for myself by putting on my /busy symbol doesn't mean I shouldn't take the necessary steps to potentially protect other innocent players from being griefed by this player (who may not know how to prevent this grief from happening).

That's fine; you've clearly thought about it. But some people just call GM to sort out their emotions and/or to attempt to harm the other player (whether or not they deserve it).
