If you miss compatibility with a specific Contact form, feel free to submit a PR in the GitHub repository or create a feature request. If possible, include a link to the developer documentation of the plugin.

In general, only non-premium plugins can be considered. These must be hookable with filters or similar.

I installed your well-needed plugin. Then added a list of “bad words”. Using a DIVI contact module and the plug-in does not block messages with a “bad word” in the content.
Am I doing something wrong? Suggestions?
