Message Filtering

Levenshtein Distance

As of version 1.0.6, BungeeEssentials implements a very basic antispam feature which calculates the levenshtein distance of the current message and previous message, this helps to prevent spam as messages that are considered to be an 85% match or higher will be blocked and the player will be presented a message asking them not to spam.

Unfortunately this makes mass messaging a pain, though it is a trade off for having the functionality there. You can bypass the filter by granting yourself the appropriate permission from the permissions page.

Regular Expressions

As of version 1.0.6, BungeeEssentials implements a basic regex matching system where you can setup "rules" (inspired by the likes of ChatControl and PwnFilter) to determine if a message should be blocked or not.

By default BungeeEssentials includes several expressions, though these are mainly for demonstration purposes and I can't promise that they are amazingly reliable (I'm not an expression god, sorry!)

rules:
    - pattern: '\bfuck\b'
      handle: CURSING
    - pattern: '^(https?:\/\/)?([\da-z\.-]+)\.([a-z\.]{2,6})([\/\w \.-]*)*\/?$'
      handle: ADVERTISEMENT
    - pattern: '(?:(?:2(?:[0-4][0-9]|5[0-5])|[0-1]?[0-9]?[0-9])\.){3}(?:(?:2([0-4][0-9]|5[0-5])|[0-1]?[0-9]?[0-9]))'
      handle: ADVERTISEMENT
    - pattern: 'asshole'
      handle: REPLACE
      replacement: '******'

For those of you who do not understand regular expressions, the middle two rules block hyperlinks and attempts to also block IPv4 addresses.

Handlers

There are 3 handlers available as of version 1.0.6, they are listed below:

• ADVERTISEMENT
• CURSING
• REPLACE

Replacement offers you the ability to replace the matched text with text of your choice, you can see an example of this above.

Warnings

The ADVERTISEMENT handler will warn a player with whatever you have specified in the configuration file and the CURSING handler will also warn the player with whatever you have specified in the configuration file.
