I See in Logs a Lot of Blocked Messages with Reason: "Forbidden. Please Enable JavaScript. Spam Sender Name."
A lot of spam bots can't perform JavaScript code, so it is one of the important checks and most of the spam bots will be blocked with reason "Forbidden. Please enable JavaScript. Spam sender name." All browsers can perform JS code, so real visitors won't be blocked.
If you think that message was blocked wrong, let us know about it via a private ticket [ https://cleantalk.org/my/support/open ].
If you or someone of your visitors has the error "Forbidden. Enable JavaScript." please check JavaScript support in your browser and do JavaScript test at this page: Check JavaScript support.
