DontUseThat

Disallow color and styling usage, block illegal usernames, filter chat messages, and stop spam, all in one!

The idea

What if... what if there was a simple, compatible and flexible spam fighter?
DontUseThat is aimed at providing a simple way to fight spam, but also to fight chat exploits, add username rules, add a more extensive color and styling permissions system, and all of that in one single plugin.

Features

Instant log-in and log-out prevention!
- Configurable rules!
- Automatic IP banning (configurable)!
Color and styling permissions
/plugins and /about permissions
Chat timeout (both message and command)
IP blocking! (block IPs in chat)
Username rules
Operator and permission-based warnings (let users with the node know an user attempted to do something he couldn't)

When?

This plugin is still experimental. I am working on it every day to make it better.
DontUseThat is a complex plugin to code. I am administrator on CreenCraft which is currently running the plugin, and the whole community is helping me test everyday. Thanks to them!
I expect to release a first alpha version soon, featuring most of the things I mentioned here.

To-do list

Word blacklist
- Allow wildcards
Username blacklist (like work blacklist but only applies to usernames)
Login logs
Command blacklist (run only from console)?
URL blocking
Command warning (when player uses commands which are considered "dangerous" (configurable))
Emergency command - de-op all players leaving the player who ran the command the only op, this command would be customizable (such as /emergency [password] or /[customcommand] [custom arguments], where customcommand would only be known by the actual physical server operators)
Economy transaction watcher (Vault dependency), warnings if big amounts get tranfered (configurable)
Any suggestions?
