[H] CSGO [W] 4 Keys

Might want to close/delete this asap.
It is not allowed to trade/sell accounts on this site and certainly not by Valve.
Posting all this info , proves you are violating Valve's ToS and will result in your account being banned/removed.

Besides, the original owner of the account can always claim to have the account hacked and get it back easily.

Ya its a scam. Even if they give email and change it all you can still contact support with your ip address and get it returned.
