Spam bots getting around captcha (sp?) in 2.2.3

Never had this issue until today. I have had about 10+ spam emails in the last 2 hours, and captcha is enabled to send emails via contact us.

Thank you for using our shopping cart.

I have had these before. Usually I just change some of the settings for the captcha and they go away.

I altered the captch ato show double digits for a day or so that stopped. Changed it back as it was confusing for customers.
