In Minecraft 1.19, the reporting system has been added into the game. If Microsoft think your message is "not ok", your account can't play with others anymore. The system seems good to keep the servers friendly, but we don't know if it's like the keyword filter in Bedrock Edition.
This plugin makes all messages in your server unreportable! And there's no "unsafe" marks.
Please note: the vanilla commands such as /w are still reportable now. I'll add the feature in the future.
