Is this a scam?

Somebody by the name of Eric Longman filled out the form submission on my website with the following message:

Hi, just wanted to inform you that all the advertisements on our website https://bankllist.us when clicked is redirecting to your website. Please check and let us know why those ads are redirecting to your website.

What on earth? Is this a scam? I did not click on the link, of course, but this message makes absolutely no sense to me. How would I even check this?

TIA for any input.
