Also got those annoying (spam)bots joining your server?
Use ServerCaptcha!
What does it?
ServerCaptcha is a plugin, which opens a GUI when a player joins. Players have to click the green wool, otherwise they will be kicked. You can configure when it opens: Firstjoin - Only opens a GUI when the player joins for the first time. Always - Always opens the GUI when a player joins daily - Opens the GUI once every reload, so if you restart your server daily, it opens once a day.
Why?
Many servers are having bot problems, a lot of (spam)bots are joining all at the same time, and they are trying to ruin your server! This plugin stops them!
ToDo
- Fix some small bugs - Add more bot-detecting features
