Spam-Customers

Hello everyone,

I have 2 questions.

1. I have the problem that I have spam bots since I use a forum plugin (Asgaros).
   So I installed Cleantalk and hoped that would stop.
   Unfortunately, I still have to manually delete fake users that are created as customers.
   I don’t know where else to make settings. The fake users have addresses like trymail.site, but also always others. I can’t ban all email addresses / domains.
   I want to keep the forum plugin. ??
2. Hiding recaptcha
   How can I hode the recaptcha symbol on my website? Its disgusting especially on mobile.
   Help is welcome!
