Spam Backlinks to site

I have a site that was marked potentially hacked by Google and when I went to google webmasters, I saw a lot of links back to my site and internal links and content keywords showing up as spam words like “porn” and others I will not list because it’s filthy.

I’ve run so many spam tests on the site and nothing comes up as suspicious. I’ve installed WP Security and Anti-Malware Scan and Askimet and CleanTalk – and everything shows up cleaned and scrubbed. I have no idea what to do or what’s happening but I would like to get rid of the porn words that keep appearing on google webmasters.

I checked my .htaccess and did find a redirect code that I deleted. I don’t know what else to do!
