Welcome to the Q&A Forum

Hi there, Spam score is determined by a separate crawler than the crawler that powers Link Explorer and updates roughly once a month. Unfortunately, even if a domain is ready to be resold,  it is never fully "deleted" meaning the spam score would carry over. To improve this score I would recommend reading our guide which explains the 27 factors used to make up this score. 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 If you have any further questions, please send a message to help@moz.com!
