   We are aware that some customers are receiving an increased volume of unwanted spam submissions through public Smartsheet forms, even with reCAPTCHA enabled. Our teams have been actively investigating and deploying additional protections. We are observing a decrease in spam activity as we continue applying and evaluating further mitigations. Who is affected: Customers who use public forms that do not require login.

   We have implemented measures to address the increased spam activity with Smartsheet public forms. We will continue monitoring and make further adjustments as needed. If you are continuing to see a high rate of spam submissions, please contact our support team so that we can investigate further.

   This is now resolved. We are still actively monitoring spam levels as an ongoing and evolving strategy. We encourage all customers to submit support tickets for any residual spam coming through so we can continue to fine tune our solutions.
