When was the report? Any proof for the date?
Well the date of report is not important. Important in my opinion is that this post was made almost 2 years ago. I understand your frustration. As hilariousandco said You should msg to theymos. Put there your apologies and explain how you have changed since those 2 years and why such an issue won't happened again ... maybe suggest that you will review all your posts and delete all shady once.
Because, you committed a crime period. Crime never dies. I does not matter which year you get caught.
Actually it does matter. Even if you will kill a person after 30 years you can't be punished for that (at least in my country - Poland). 5 years is enough for low harmful crimes.
