I am not on any leaderboards, i registered at r6tracker website and i linked my uplay , steam , discord and twitch and selected my country but i’m not at leaderboards . i dont have any bans and i verified my ubisoft profile
It may take a few hours for new accounts to show on the LB’s 
If you have further issues let us know and also provide a link to your account and understanding of which specific leaderboard you are looking into.
Thank you
