-Keep disabled guest posting. By default, the forum permissions are set to allow guests only to read the topics and not to reply to posts. If it's important for you to allow guests to post, make sure that CAPTCHA (visual confirmation) is enabled for guest posting. -Check to make sure that CAPTCHA is enabled for new registrations. It's enabled by default. Make sure it stays that way. From the Spambot countermeasures settings of the admin panel you can also make the CAPTCHA image more difficult to recognize, so that it is more difficult for spam bots to register. Please tell me!
