I didn't understand anything. In the post you provided, everything is deliberately explained vaguely without going into technical details.
Autoban is when the system automatically bans without moderator participation? Right? But by what criteria? By IP match?
I’m not sure if it doesn’t require a moderator’s input, but autoban usually means it’s automatic and permanent. From what I’ve observed, the main reason for autoban is plagiarism, which is clearly against the forum rules.
