My site was disallowed from advertising on Google when using Matomo analytics
I think you're reading far too much into this.You spoke with a support agent who is checking the status of your AdSense campaign. That system has flagged links on your website as 'malicious'. The agent is simply telling you the links are 'not allowed' because the system has flagged them. Ie. you're not allowed to run AdSense on a site with flagged links.I'm 99% sure this has nothing do with you using a GA alternative.
