Absolute newb here, please forgive me for this basic question.
I have built my portfolio site using Github pages, but am experiencing spam via my contact form (hosted by GetSimpleForm). I am trying to implement Google reCAPTCHA, but I'm a bit stuck in the backend part. As I understand, Github pages don't support PHP, so I can not actually complete the form verification.
Google documentation here was unfortunately a bit overwhelming and cryptic to me as a beginner, since I just stared at my Github html/css/js files and had no clue what to put where.
Am I trying to do the impossible? Is it possible to use reCaptcha on Github pages? If so, is there a beginner friendly tutorial somewhere or a straightforward "copy-paste" thing I could use? (so far, it's not been clear where to use the secret key from the API key pair for example)
Thanks a bunch for any leads or alternative solutions for spam prevention that would work in Github pages!
The short answer is you cannot. Github Pages only support static site. You have to host your own website if you want to do some complex stuffs like backend check etc. and mostly they are not free.
The only suggestion I can come up is simply change your contact form to regular html form instead of hosting by the 3rd party website you are using. I suspect that the main reason you got spam is because you are using it's service.
