• Why am I getting this message?
• Are deleted posts taken into account too?
• Is a question/answer ban the same as a suspension?
• How do I avoid getting a question ban?
• How long do I have to wait before I can post again? What can I do to release the ban? How can I reactivate my account?
• Can I simply create a new account?
• I'll just ask on Super User or Server Fault, and they'll migrate my question to the correct site!
