bendrey I have heard back from the team and they have confirmed that your website hasn't been blacklisted by Google. We have also been able to get the charity ads to show, which confirms there is nothing stopping the ad placeholders from working.
To continue troubleshooting this please can you open up an adsense account and link it to Ezoic https://pubdash.ezoic.com/ezoicads/adsense/linkadsense and we can then see if there is any adsense ads that pull through to your site through the mediation.
I have also noticed that the majority of your traffic is coming through Facebook please can you confirm if you are paying for ads to draw this traffic to your site? thank you
