If you go to Help -> Abuse -> Common Offences, there is a more detailed list of reasons why one may be silenced. If you go to Terms and Conditions in the Help section, you can find Posting and Forum rules, alongside the Privacy Policy and ToU. This may be misleading for certain players as they may view these to be the only ways to get silenced, and this thread lacks a fair few of the possible reasons and details about each. Locking.
