Welcome to the Q&A Forum

As Samantha mentioned, the Spam Analysis tool is not a 100% accurate tool, it's more of a 'helping tool'. With the tool its best use is to get some ideas on what poor links are pointing towards your site. Even then you need to take the results with a grain of salt. The tool may give you a spam score that is not entirely accurate, you need to examine the links and make sure it is actually spammy. You'll also notice that the tool doesn't pull all the back links to your site. Moz doesn't have the capability that Google does to crawl that much quantity. To get a complete list of your links go into Google Search Console. If you're seeing your rankings and domain authority increasing this is a good sign Google noticed your disavow. Hope this helps.
