Description:
Person is attempting to go on multiple sites (playdota, reddit's /r/dota2trade, etc) and manipulate the price of a Dota2 unusual (Unusual Diretide Yak), by placing (under other names) offers to sell yaks at 30-35 keys, and under other names to buy for 37.
Person will accept add and talk as if he is intending on purchasing, but will ignore all trade requests.
