The Moz SPAM score doesn't directly measure Google penalties. It predicts when a penalty or ban might be assigned to a website by looking for domain, on-page, and backlink warning signals that are typically present in penalized or banned websites.

The snapshot you provided shows Google with a spam score of 2. That means Google itself is exhibiting a few of those warning signals. 2 is a low score, meaning there is a low likelihood Google would penalize itself.

Moz has an excellent post explaining what the SPAM score is, how it was developed, and what it means. It lays out the different warning signals and recommends potential uses for the spam score.

Hope that's clearer. If not, let us know or search Moz for "Spam Score". There is more than one useful explanation.
