Is trading account illegal?

was just wondering a friend traded accounts but the other guy is reporting for it back can my friend get banned?

my friend was given the email and the account so he changed the password...

or can he be banned if the guy said he stole the accounts could there be proof?

Well it's not safe to trade accounts online, you can get banned if you scam the person. Does he have any proof of him doing this?

its illeagal haha
but no1 ever catches youu
basically its jus not safe no1 ever actaually wants to trade accounts its jus a scaam

wow that messed up csm2 with .4kdr, and on a hacking forum??
