Google has recently announced policy changes that would make it impractical for us to continue using their invisible reCAPTCHA v3 service.
I have removed this service from our pages, replacing it with Cloudflare Turnstile in only certain parts of the site (login, registration, contact and PM).
You will notice that a new test will appear on those pages, but not everyone will see it as, with time, it will get smarter and only show the test if needed.
