I've got a new client and I'm trying to clean up their backlinks. There are several links that all redirect to this spam site http://www.expert-lender.com. All of the websites appear to be real, i.e. http://www.sammorganhomes.com/ but the actual links i.e http://www.sammorganhomes.com/wp-fav/backup/supplement/semitruckleasing.html are in a sub-directory and redirect to the spam site. I don't know if these links were from the previous SEO company or if they paid someone to create these or if these sites have been hacked. Can anyone tell me what is going on here and what should I tell these site owners?
