What's the best way to get rid of hacked content that is being redirected to spammy links? Do you recommend a noindex tag and 404 not found for every page or is there a better combination? And if I do use the 404 not found, should I add the noindex tag there as well? In what kind of a scenario does the Google URL remover tool help since it comes with a rider that the content may be back in the SERPs after 90 days? How often should the Google Disavow Tool be used?
