Is there any issue with linking in this directory? jsum dot org

Also, is this correctly called a link directory or link farm?

The site does not comply with Google Guidelines. One example is it accepts paid links and does not add the nofollow tag. It is likely all links from the site are penalized and have no value. I would not recommend obtaining a link from this directory.

With respect to "link directory" vs "link farm", I am not aware of a formal definition but this site would be both a link directory and an article directory. A link farm commonly refers to non-directory sites which exist for the purpose of providing links to manipulate rankings.
