Hello Yo ID Banned for “Serious Violation”

My Hello Yo ID with the username “Ikera k***” and account number 1589444*** was suddenly banned today for a so‑called “serious violation.” About one hour before seeing the ban message, I was simply chatting in a room, and I did not commit any intentional violation of the rules. The ban notification appeared when I tried to log in again, but I was not given any clear or detailed explanation about what exactly I did wrong. This situation has upset me because I use this account regularly and want to continue using the platform within the rules. I request that my Hello Yo account be checked again, the reason for the ban be clearly explained to me, and my ID be unbanned if there is no valid or serious violation.
