I'm facing an odd situation, I've added site as property to google search console in this april, around last week i checked that search query, site:my-site.com was showing links for pages which I have never created, they all had happening.pk title in it. Their cached version showed content from happening.pk and while I clicked on them, it goes to my site with 404 content not found. I requested google to remove all outdated pages here and google approved the request.
Next day all weird search results were gone. Now google re crawled my site recently and I'm baffled to see that all happening.pk results have reappeared. My host did checked for malware and says my site is clean, checked with sucuri, says its clean. Google doesn't have any manual or security action for me. In coverage in google tools I can see that there're more than 200 excluded pages with crawling date from January 2017 to May 2020. And I don't recogonize a single of them, all are happening.pk pages. I started creating my site from March 2020, moved to premium host in this May and created site from scratch without migrating anything.
How do i get rid of these happening.pk search results for google search query, site:my-site.com. Also I can see that pages I published are appearing in google coverage but not in search results for site:my-site.com. Please guys provide some guidance.
EDIT: these pages are visible in coverage under anomaly. Shows last crawled date for a particular page like my-site.com//uncategorized/bunvat-festival/
Feb 2018 but I've removed this page two times in this month. For 404 pages crawl date was in may 2020. Under my coverage it says that URL might be known from other sources that are currently not reported. Another thing is my site is completely https whereas these urls are http: //www only, can it be possible that the source of these urls are not from my site.
