I see. I'm not aware that changing emails or passwords will lead to account locked. But regardless, I'm glad now that my account got locked as it might post more malicious links without my consent.

I already sent an email provided on the ban notice and waiting for the instructions. I also reached out to Logitechmouse to share with me some details on his former case and what steps he did in retrieving his account.

Thanks for everyone's response. I truly appreciate it. Your shared information is feeding my mind and if the same case in the future happened to anyone, this thread can serve as a reference.
