There were still bad intentions behind your messages, "I have your IP address" there would be no reason for this to be said at all unless you're trying to threaten someone and in this scenario we believe it was indeed your intention.
This situation could have been completely avoided had you just kept to yourself, I do not believe you're worthy of a time reduction but instead to serve out the full length of the issued ban.
So therefore I am denying your appeal - If you are not happy with my answer please feel free to approach Mike , posting another ban appeal will ultimately end with you being forum banned so I advise not trying that.
