Questionable links and traffic

are they connected

I have a site that used to get nice traffic then about 6 months ago i started to notice some stange referrers to pages that no longer exist...is this some sort of scheme to kill a site? Any insight would be great

Log spamming [webmasterworld.com]. There are no links to your site.
