Issue with Blind Form Spam Protection

The blind form is quite useful for email tracking; however, there has been spam issue with the feature. Eloqua has developed a new feature to fight against the spam problem. I have tried this feature once a few years ago and had to cancel its use due to the negative effect on the integration of external tracking (using custom-defined parameters like utm_campaign, ...). Somehow the integration of the feature will stop the integration of these parameters, of which the values were missing in the submission data.

I have tried this feature this year and felt so disappointed ☹️ that the problem has not been resolved and was forced to deactivate the feature.
