Hi @jreedpasd
Hyperlinks are not usually considered malicious HTML and because of this are automatic sanitization. In many web forms hyperlinks need to be allowed simply for the form to function the way the owner intended.
That said, the Pro version of our plugin has conditional logic features that can display a warning and disable the submit button when a hyperlink is added.
We can only support the Lite plugin here, but if you are a Pro user or would like further presale information about this Pro feature, could I ask you please to open a ticket in our helpdesk here: https://formidableforms.com/new-topic/
Thank you!
