contact form spam and recaptcha

Hi, I have a few screenshots I would like to send to your support (private, not put on forum) is this possible?
I’ve had a nightmare with Enfold for almost the last year I get lots of spam, mainly russian origin through the contact form. My server admin sent me a link to the main email address that’s used to send out the form emails and it’s a list full of requests with ID’s, maybe your support knows what they are. What I tried till now without success: add the Really Easy HTTPS plugin, worked to get things more secure. Tried to disable the ‘equation solving’ as your form says it had some hidden antispam built in (no difference). Tried to delete the page and made a new contact form in Enfold (cause because of many tests and changes in the newest WP the page just broke, my WP and also Enfold is set to automatically update, but WP’s Avia builder is now looking sort off a mess). I also tried Akismet, seems to make no difference. Now I noticed my Google maps API key wasn’t working anymore, so I deleted it and made a new one, doesn’t matter if I say no restrictions or try my domain name as a restriction, the “test API key” doesn’t work, when I screenshotted that Google APIs shows its active and had requests. Then today I made some Google ReCaptcha v3, i have both keys but not sure what to do with them. I’m considering making a blank page and test Contact Form 7 where this ReCaptcha is built in, to see if that stops the spam. My mail provider told me, as I’m getting refused MX google records, that Google seems to ban my domain because of all the strange activity, not very helpful if you’re getting desperate to find clients to work with. Perhaps these can be jealous developers who hire such hackers to try and put me out of business by trying Google to think my domain Is a spam source, I don’t know anymore what to do? Feel free to mail me back and I will forward you the screenshots! Have a nice day! Best, Ike.
