Let me leverage on this question and learn please. I have been seeing autoban especially when Lovesmayfamilis reports cheating or plagiarism accounts.

Permanent ban: Means the user is banned permanently and not supposed to return to the forum with another account. Though the user can appeal and get lucky in rare cases.

Temporary Ban: Means the user is banned for some days, weeks, months, years as the case maybe. The user will return to the forum after serving the ban punishment.

Signature Ban: Is allowing the user to use the forum but not using the Signature space.

What is AutoBan and how does it differ from Permanent ban?
Does it work as the name implies? Which means no moderator bans you. Maybe the ban is triggered automatically by the system codes? If no, why is it called Autoban?
