Facebook Locked Me Out of My Account With Years of Messages and Memories

I have been actively using my Facebook account for many years, but for approximately seven months, I have not been able to log in at all. My account was suddenly disabled, and I never received any information, warning, or email explaining why it was closed. I have had this account for 7–8 years, and it contains private messages, my circle of friends, and personal memories.

I am not aware of having violated any rules, and to this day, I have not submitted any formal appeal regarding this issue. I am requesting that Facebook explain why my account was closed and that my account be reviewed again and, if possible, reinstated.
