There are some very spammy linking domains redirecting to your site, for example: www.jyztpk.cn (spam socre 98%, DA 1)

I wonder if this is because you acquired a new domain and not because of the core update... You might have inherited all those bad links when you claimed the new domain.

Hi there,

To quote Moz staff on this,

So, 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. 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

Best of luck, and let me know if I can help with anything else!

Hope this helps!
