Welcome to the Q&A Forum

In Feb, 2015 www.mommyupgrade.com site received the following notification in GWT: http://www.mommyupgrade.com/: Suspected hackingFeb 4, 2015
Google has detected that some of your pages may contain hidden text or cloaking, techniques that are outside our Webmaster Guidelines.
Specifically, we detected that your site may have been modified by a third party. Typically, the offending party gains access to an insecure directory that has open permissions. Many times, they will upload files or modify existing ones, which then show up as spam in our index.
Sample URLs:At that time,  the site was checked by the host and site owner and any suspicious links removed. We thought the problem was resolved until a MOZ crawl on March 22 which highlighted a number of hack links again. This is the link format: http://www.mommyupgrade.com/?p=online-slots All are related to gambling, casinos and slots. To find the links, we downloaded the MOZ crawl report and found that all the links were referred from this page: http://www.mommyupgrade.com/how-to-make-rainbow-lollipop-cookies/ Searching that post shows no sign of links to the rogue pages. I would really appreciate some advice on how to find the source of these links and delete them from this site once and for all. Also, please explain how it is possible for a post or page to refer to another page without that link showing up in the code? (Is this some black hat technique that I need to know about in order to protect my sites?) Also... at the moment Google Webmaster Tools are not reporting any security issues for this site. Any help appreciated.
