high level of scamming activity

i noticed lately a high level of scamming in icecrown serveur.Whenever i try to sell an item that i hardly worked to get the mats to created it the buyer/scammer always tend to buy it for amount of gold that included zeros like 10000 or 15000 ,as soon you put the item in trade and he put the amount gold you two agree on,he delete a 0 and try to quick trade you so you ended up with 1000 instead of 10000 i dont know if this is illegal in the serveur.in this case i wish that i had a video recorder :/

It's bannable if you report them. Since you don't have screen recording software I guess you could save a series of screenshots for each trade. Just make sure you report them to a GM through the ticket system as explained here.
