rsprod scam

well some1 added me today pretending he wanna buy my steam account i said ok i will go first since he had way more vouches than me and i asked for a confirmation message on sythe, he said that sythe is bugged and he can only send me messages from his e-mail . the problem is that this guy really had acces to the email and sent me as u can see in pic, but probably didn`t wanted to risk posting to my thread or message me on sythe. what can be done ?

Unfortunately this completely lacks proof and that can be faked via Email Spoofing, sorry.
