New Trade Hack

[TYLER]

obviously, there's a new trade hack cuz i just got ripped....i was just lookin through games, lookin for some trades, when i see 'enigma 4 pul' ...yea, i knew it was a scam, but i was bored so i decided to go in and see how slick the scammer was...i went in, necro comes up to me...puts up enigma...i put up pul...he says, 'lemme see ur shield', i put up my sanctuary..he says, 'throw that in, its a deal', i say, 'no, game says pul'...so i put my sanctuary back on, and check to see if enigma is still there, its there, and then, he checks (green arrow) im like, wtf?...so im like, what the hell, he might be a noob...so i triple-check that enigma is still there up to the last moment, and when i check (green check), and trade window closes, i look and i have shitty 14 defense armor......so obviously there's some trade hack out now that switches the item right when the other guy puts up tha green arrow...prolly gotta have a fast connection to do it smoothly too....luckily it was just a pul....
anyway,
has this happened to anyone else???
