@webnewsobserver Hi, Moz Spam Score at 11% may be a matter of concern for your website.

But there is only one way to reduce this. For that, you have to maintain good-quality backlinks for your website.

One way to do that is to remove spammy backlinks and the other way is to keep making good-quality backlinks so that percentage of bad backlinks becomes less.

The second method is tried and tested and good in the long run as you keep adding good quality backlinks. I reduced spam score of my own website https://bloggingidol.com and yes don't forget to check article recommended by Moz Staff @jocameron

There is a limit of 10 free searches on Moz free account. If you want to check more you have to go with Moz Pro. And as @Fabian001 told you can use free tools. There is one more tool keyword explorer which you can use to check backlinks from SERP result. Simply install this extension and you are good to go.
