Hey @BIVANBLAZE13. I just saw your posts on on my Scammer Alert Post that how did I know Matelinski is going to scam you. within these posts I have attached some screenshot of me being scammed by him badly. As soon as I got scammed he blocked me so I went to see his profile. He was browsing you, so I messaged not only you but 4 to 5 players who were being watched by him continuously after me getting scammed. Just a heads-up it was.
Furthermore i'll give you a whole list who matelinski aliases within the game:
4. Yelty (This one is his most recent shift)
I am guessing he has one more where all the traded pokemon are shifted. i can only trace the IGN where the money is being routed
