Players figured out that they can type "&6 example" to get in-game colored text.
As you might be able to imagine, this resulted in instant spam forcing me to deny players to type in the channel.

Even though "stripMinecraftCodes" is set to true, this still happens, with no other config option that relates to this. Please add an option to also strip these color codes.

👍 to this idea

I think in the meantime, you can probably add a rule to to messageIgnoreRegex in your config.

Or issue bans to people that are breaking your rules.
