if you believe that the script you uploaded was not a null script (e.g. the script was either freeware, or you have a valid license for the script), and can prove your case (such as linking to the site where you got the script from to prove it's freeware, or having a representative from the site where you purchased the script confirm that you hold a valid license), then you can request that the suspension be looked into. If this suspension was indeed a false positive (meaning you did not upload a null script), then your account will likely be unsuspended.
If you don't have proof or you did indeed upload a null script, then your account will not be unsuspended and will be terminated in 10 days.
