I was checking a few domain names that I had liked. They had no backlink, but high spam score. I have read somewhere that moz doesn't get to know, if a domain name has been disavowed. As now no domains are not linked to them, should I buy them?
Wait, isn't the spam score a "lower is better" metric!? I believe so. And it's related to the CONTENT sitting on the domain, not the domain itself. Isn't it? In this case, the spam score isn't really relevant, except maybe penalizing the domain for a while due to past content. But that shouldn't last over time (with good content).
In any case, you want LOW spam scores, not high ones, if I'm not mistaken.
Oh, the SPAM score would be because of links pointing to the domain, and NOT content, as I wrote erroneously above. And I guess I misunderstood the initial poster question then: He was asking if he could still buy the domain despite the spam high score, isn't he? Not that he wanted to buy it because of it (what I understood).
I consider that any worn pants can be cleaned and worn again, similarly with domains, the content is important and services provided, if your services are in high demand you can host your website even on dgngidg0hndi8ughiu:com and search engines will do the rest for you, you even will not need to run ads, your end users will do it for free, this is based own my own experience, of course a strong domain will yield more traffic to your web.
However the never used domain might be a better choice.
