To prevent automated software – known as spambots – from creating bogus accounts or bombarding your blog or forum with spam posts and comments, you can enable Wild Apricot's anti-spam Captcha feature. You can enable or disable Captcha separately for different types of forms, including membership application forms, event registration forms, forum posts, and blog comments.
With Captcha enabled, visitors to your site will have to enter a set of characters – proving them to be a person rather than a program – before they can submit the form.
Using a form with Captcha
If Captcha is enabled for a particular type of form, the form will include a Security check section towards the bottom.
The section will display a group of distorted random letters that the user has to enter before they can submit the form. If the user cannot distinguish the letters, they can click on the speaker icon and have the letters read to them or click on the refresh icon to get a new set of letters. There is no limit to the number of attempts they can make.
Once they have entered the letters properly, they can proceed to the next step.
Enabling Captcha
To enable Captcha for different types of forms, go to the Website module then click Settings within the menu bar at the top of the screen. On the screen that appears, Anti-spam settings (Captcha) under Website security. From the Anti-spam settings screen, click the checkbox beside the desired form types then click Save changes.

Note that anti-spam settings cannot be turned off for the public on certain pages like blogs, forums, send message forms, and subscription forms.
You can enable Captcha to appear when forms are visible to the public, just members, or both.
Within Captcha settings, logged-in non-member contacts are considered public visitors.
