ChatMod

ChatMod is a simple, lightweight plugin that scans messages for spam and blocked words.

The plugin will check if someone is sending messages too fast, using too many capital letters, spamming the same letter repeatedly, or sending certain harmful slurs.

Basically everything is configurable, from the list of blocked words (if you want to add and remove any), to the thresholds for capital spam and letter spam, to the minimum allowed duration between messages.

For more info about the plugin, including a config and permissions guide, you can read its readme here.
