What's the message you see after you login to the forum?
There is no record of ban for your account in modlog which means that the account has not been banned. Of course, since temporary bans are not displayed in the modlog, there's a chance that your account has been banned temporarily.
Sorry harizen, you are banned from using this forum!
For security, your account has been locked. Email ...Anyway, I already followed the instructions here and hoping for good progress.
