Hi Georg! Not a problem! Moz's Spam Score is the percentage of sites with similar features we've found to be penalized or banned by Google (it's not based on the spam score of the sites linking to you). To improve this score I would recommend reading our guide which explains the 27 factors used to make up this score (we don't identify which ones specifically are affecting your site within the UI). You can then look at your site and investigate areas you would like to improve on your site: https://moz.com/help/link-explorer/link-building/spam-score
