Broken reCAPTCHA check for Account Signup

I'm possibly not posting in the right place, but I've seen an issue reported on Reddit a couple of times over the past month - people can't make an account here due to the reCAPTCHA security check being broken on the signup page; "ERROR for site owner: Invalid Site Key" - Link to reddit thread with an error screenshot (since Imgur has blocked the UK and I need to find a new image host *annoyed noises*)

I checked in a few different browsers just to make sure it's not browser-related, but the issue persists.

Just a heads up since I don't know if anyone was aware of the problem!

That would explain why we haven’t had any new members for the past month… 🤔
