This website does collect personal data. Google's FAQ on GA simply states that the first party should obtain consent before transferring data to a third party (and transfer of consent might not be GDPR compliant, but that's another issue). Here, the first party (analytics-bypassing-adblockers.netlify.com) has to obtain consent before collecting personal data. And IP addresses are not the only personal data that GA can collect.
