So, my brother has 93 fletching and he's a MAJOR fletcher. One day, he gives me 9k mage longs and 9k nats and tells me to high alch them all, so I do. Then, he tells me that 12 mill or so and buy 12k mages (magic logs), so I go to w 9 like normal and (without using autotalk) try to buy 12k mage logs. After 20 minutes or so, a guy trades me and puts in 12k mage logs, so, using my antiscam technique, (have 1 noted mage log in inventory and money, fill the rest with junk), the guy had actually put in 12k willows. I declined and reported him like normal, but a if he read my mind, he aplogized and traded me again and put in 12k mages this time. I dropped it and saw a guy buying 1 pure ess 1k, and I had one in my inventory for antiscam purposes. Then the scammer trades me again, and puts in 12k mages. I put in 12m and click accept. Then, he puts in 12.1 mill and says "Match," so I finally give in and put in 12.1m. He accepted and took out the money, but my brother was watching the whole thing and dives to the computer and clicks decline. I was wondering why, at fist, then later, I realized that when he put in 12.1m, he'd changed it to 12k willows again. Not having my antiscam anymore, he had taken advantage of this and switched it all up. I can't even imagine how mad my bro would have been.
