I had a similiar issue and i was able to fix it. First download Wordfence plugin or similar. Once you run the scan, the result will show all the spammy pages associated with your site. It should look like something like that www.yoursite/spampagename Then locate this page in your Cpanel > public_html> spampagename Delete the page Do this for each spammy pages. Then Go to your Google console and inspect all your pages. The spam pages should show somewhere (they won't be indexed). Delete those pages, then click on "fixed". Google will run your site again and in a couple of days, log back in the console and all the bad pages should be gone
