Delete unwanted URL (opens in new tab)

I want to block a URL\. Someone sent me a question from this site and now I wish to delete/block this site\. I don't have an account with this site, so all the usual ways to \"opt out\" are unavailable to me\. I've checked online for answers, but none have been able to provide the answer\. I think my problem is that I'm not a member/did not sign up to this website\. Android 15 O\.S\.- gmail TNX
