My twitter account was suspended two months ago. I followed all the steps to have it restored, after about two weeks I received the information you listed from the employees at twitter. They gave me reasons why accounts can be suspended but never advised me of how I broke any of those rules. I asked if they could restore my account but they said that my account was suspended and would not be restored. I had my twitter account for two years and had worked it up to over 6,000 followers and over 15,000 tweets.
