adult keywords (anchor text) to link to the site.
to link TO your site?
Many times what hackers will do is plant stuff on a clean website (your site) and then build crap links to your site to try and build up the authority of your page so that the link they planted has more value.
Why else would someone link to your site using adult keywords if your site is not adult (just assuming its not)? If I was going to do negative seo to your site i would use keywords that I don't want you to rank for so that you get penalized on those keywords.
