nope. aint gonna advertise what website I bought my platinum. but how it work is just like that you said. I used an alt account with safety precautions using different PC, VPN, Changed HWID, and changes my wifi address. Basically I bought 2,000 plat and Directly traded to my 2nd account. then using my main account I posted an item for sell in WF trading and DM my second account using my main. Had conversation to myself lol cuz not sure if DE are monitoring the in game chat you never know. So basically using my main account I traded a decent item like arcanes with maximum rank to my 2nd account with 2,000plat. then voila I still got the negative plat on both of my accounts lol
