Hi, It appears one of our comeptitors website has been hacked (or its some seo tactic ive not heard of). However its actually helping them in the serps. Basically from what I can see someone has got into there website and is placing hidden (to them) pages on there website with random scraped pictures then linking to hundreds of other hacked websites with different anchors such as "barbie pictures to colour in". It is also linking back to these random pages with similar anchors? Now is this some sort of SEO tactic or what isit? Thanks.
