I have 301 redirects from my old URL to the new URL (and from http to https, and from no www to www)
The link suggestion you provided just offered a link to a you-tube video that was instructive but did not help me.
I found a link to https://support.google.com/legal/troubleshooter/1114905 which allowed me to "report content that you would like removed from Google's services". I submitted a request that the scrapper site be removed from Google's index.
