i was trading on a trade server cause i resently got back into tf2, and thsi guy traded me saying that a 1.33 ref strange bone saw was worth 10 ref so he wanted my square dance taunt, i said thats its not worth it and i said ill pay 1 ref for it he claimed to not know it was 1.33 ref but when i pressed ready he removed the item and pressed ready then i exited trade, 1 hour or so later he traded back BEGGING for my killstreak strange minigun worth 30 ref but all he added was 1 ref worth of wepons, he spammed me by saying "plz pl pl plz plz plz its my first killstreak" yet in his backpack he has a killstreak medigun. this guy is very arogent and anoyying and i worriey for new and unexperened traders whom go near him and all i can do is hope valve/steam do something about it....
