Strange links on my website
I have an issue tht is bothering me for months now. I have a website and every 2-3 days - links to "fake louis vuiton bags", "reg hot shues" or "rolex replicas" appear on some of the pages.
I am keeping all pages as html content in the database and extract it as needed. I have a CMS written by myself and I am using CKEditor as a WYSIWYG user interface.
Furthermore, I have noticed that, if I remove the admin interface (CMS) - basically the only way to write to the database, the links stop appearing.
Could you help me find the problem?
