We’d like to clarify that Spotsaas does not create spam backlinks. All links from our platform are contextual and primarily nofollow, meaning they are not designed to impact or manipulate SEO rankings.
We’ve already addressed this with you over email and shared details on how this has been mitigated from our end. In many cases, what appears in webmaster tools comes from third-party scrapers or external sites replicating publicly available content — something outside our control and common across many platforms.
