Phishing Detection in Microsoft Forms

TobiasAT According to the announcement in the Message Center, the detection is performed at design time.  In my testing, it appears that as long as you do not try to edit a previously created Form, it will not be audited for phishing.  Below is the specific language from the message center:

This new feature will be applied to all public forms (when forms setting is “Anyone with the link can respond”) created within your tenant. The automatic detection will be running at Forms design time and if any suspicious phishing contents (i.e. what’s your password?) are detected, the form will be automatically blocked for sharing and response collection. This would not be a permanent block as the form can be unblocked if the form designer removes the suspicious phishing question.
