Marketo forms: Prevent adding HTML links in open text field?

Does Marketo provide the ability to prevent users from adding html links within the Marketo form (Field Type: Text Area)? We had a phishing attempt on one of our contact us forms trying to take you to a malicious page. 

 

What do we need to adjust so these can’t happen?

No, but you have to realize that mail clients (most notoriously Gmail) will hyperlink sequences of words that just.happen.to.have.periods.between.them. Even without or http:// or https://. So the solution is to throughly sanitize output, rather than trying to catch all types of input. I wrote a blog post about this a long time ago.
