OP LEGEND Facebook-Linked Account Banned Without Clear Reason

I was using OP LEGEND with my Facebook-linked account when my account was suddenly banned. I did not receive any clear explanation about the reason for this ban, and I do not know why my account was restricted. I request that my account be reviewed in detail and that the unjust ban on my Facebook-linked OP LEGEND account be lifted if there is no valid reason. I also ask to be informed clearly about the reason for the ban.
