While doing some backlink research of similar ranking sites I noticed that a few of them had links from a directory called Infignos, it has a moz DA of 37 and a low spam score of 3, so it doesn't look like complete junk.  But the posts on it look terrible, like people are just putting keywords with a small description to get rankings. Should I bother posting something similar to be competitive or just move on?  Any advice or feedback on this is much appreciated, I know some of these things are not quality sites but I was wondering the best way to filter that out. Thanks in advance.
