Getting toxic backlinks from network of print and online news publishers

Looking to know if anyone has done MAT releases on sites like brandpoint to get backlinks?

A MAT release is a branded, consumer-facing article that is distributed to a network of print and online news publishers.

These articles allow brands to leverage their own content and the credibility of third-party media companies while reaching consumers on the local news sites they frequent daily. 

Based on SEMRush some of the links are coming back as high toxic due to mirror pages. They found several identical pages on different domains linking to my site. They say it is a strong signal of link network. Which I get. but has anyone experienced this before?
