Thanks @seo2025. I have gone through the link you sent and that seems the logical step. But is there any way to export the links ? Google webmaster shows me the links but with no option to export them.

My sitemap has only 3K legitimate links but google webmaster shows 500K links indexed. All of them are spam links example of such links are as follows. Some links are referred fro

https://www.mywebsite.com/adina/1484652

(URL might be known from other sources that are currently not reported)

How can I remove them, i can't put a manual one by one removal request on webmaster
