I see that the suspension reason is for inactivity. It is a requirement that you log into these forums at least once every 31 days to keep the account active.
Logging into account panel and/or cPanel does not reset the timer. Requesting unsuspension does not reset the timer.
Before requesting unsuspension it is recommended to login to the forums to avoid having the account flagged as inactive again if there's a check run before you log in to the forums after unsuspension of your account.
