Issue with a hаcked website. Bulk URL removal from Index?

[AlwayzBluFFinG]

Hey, SEO ninjas

So, one website we take care of (since recently) was hаcked and lots of (7k+) new pages seem to be generated in the /blog directory. They are not live at the moment (Oops, This Page Could Not Be Found!), but indexed in Google (https://nimb.ws/Dsqfou). So, as we talk about 7000+ pages, what should be the best approach to remove them?

The website is more of a presentation type of a website and I don't think SEO-wise it will be important in the near future. Still, it will be good to remove those results from the index.

I've found there is an extension that lets you upload a .CSV file with URLs and do that in BULK. However, I have never tried it ( WebMaster Tools - Bulk URL removal ) and it turns out they made it paid some time ago.

The issue is now fixed afaik but I know it might take a while for Google to remove these pages from the index organically. The hаcked pages do not appear in the sitemap.

I guess one option is to remove the whole /blog directory through the Removals feature in SC? I found a resource where I believe they mention it could be used to remove not only single URLs, but a whole folder? Even if this is correct, we do have a couple of real posts in the /blog directory that might be to stay (~10ish). Still, if there is no other option, I guess that would be the optimal solution to go for.

Your strategy is exactly right. So focus on it.
Remove them from Google using the webmaster tools.
And no they are not paid yet. Those tools are still free.
Bulk removal is the only option.
I hope this helps!

Thanks a lot @RuskinF! Always good to get a confirmation on your thesis. Actually, I already did this and in a day the results disappeared from the SERP. The only issue is that when you type site:[website URL] it still shows the large number. In our case: About 7,370 results. But then you go after page 6, the hаcked pages are gone and the pages update from 27 to 6.
So, it helped to remove them from the index. Maybe just a little more time is needed for G to fully update the info. The same issue with the 2nd website, it says over 3000 results, but when you click below page numbers then they are updated and no pages show.

Sometimes you need to get multiple URLs out of the Google search results, either because you’re cleaning up old content, or perhaps you got hаcked, or for whatever reason, you want them gone.  Google Search Console lets you remove them, but only one at a time, which can take forever.
