Bukkit

• IMPORTANT: The ability to disable chat flow was broken/never implemented since it's been added. This is now fully functional, just set flow-enabled to false to disable Chat Flow.
• Metrics should now be tracking chat overflows, or whenever chat flow detects that the flow of chat overloaded.
• CAPTCHA Support Now you have the option to use AntiBot's captcha instead of kicking/banning users whenever AntiBot detects spam/flow/multiple accounts/bot spam. I will update the pages in a few minutes.
• Variety of new configuration options for Captcha support.
• Met your mother last month.

There could be times where the plugin may not help you in a spam attack.

The bot kick handling might kick innocents if AntiBot gets triggered as soon as the innocent player joins, or is the last player that triggers AntiBot.
