It can be concerning because sometimes suspicious form submissions are obvious, but they can also appear convincing. If you feel that a Contact Form submission that you received is suspicious, take a look at some of the options below to handle these instances:
Don't click on any links
Don't contact the person
Delete the person from your Contact list
Add a visible reCAPTCHA to your Contact Form(s) (if you don't have one already)
Consider creating an email filter within your email provider to prevent future contact
At this time, there is not a way to block certain email addresses from submitting Contact Form's through the B12 platform.
