my friend is also blocked
he was playing from my pc and they blocked him. because of several accounts and now he wants to verify himself and crypto.games does not send a link
Firstly, if it is a true story then it is completely your own fault to let your friend use your pc and play in the same site where multi accounts is not allowed.
Secondly, nothing you can do except contacting support and prove that you are both different players.
Last but not least, be prepared to accept any decisions from crypto.games.
