Paid Subscription Directory with Low Moz Open Site Explorer Spam Score

[aua]

Looking at different backlinks of my competitors and came across a few directories that require a 1 time payment for the year.  Is this considered the same as paying for a link or would this be considered something like getting a listing on your local Chamber of Commerce site?

Also, I put the site through Moz's Open Site Explorer and it had PA:22 and DA:20, which is nothing incredible, but also had a spam score of 2. So would a site like this hurt my rankings? I know that's a good spam score, so I am a little confused with what to do.

Here is the site: http://scl-online.net/en.htm

Thanks for any help! Love this site.
