Hello ttem,
Thanks for reaching out to us!
We’ve had several users noting an increase in SPAM since the latest update. We apologize for the inconvenience and are working on including a captcha field option in an upcoming release to help curtail the SPAM.
In the meantime, we do have a solution that just involves uploading a couple of plugins to your site:
Once these plugins are uploaded, you should see a new captcha field added to the frontend of your site’s event submission form. This should help to curtail the SPAM attacking your site.
Let me know if this helps.
Thanks!
