Now, ask yourself WHO's coming up with the supposed "high spam score". WHERE does the metric come? In my experience, it doesn't mean anything. I've seen a LOT of spammy sites with low scores and an EVEN GREATER number of websites with so-called super "high spam scores" (well above 11, sometimes 30) that ranked first on Google. You just have to care about 2 things: rankings and traffic. The SS belongs to those stupid metrics which say nothing about a website's potential. An example. In France, you have a website called "K2". Their spam score goes through the roof. But it ranks first in no time on any keyword they intend to. And it's been going like this for 10 years, as far as they're concerned.
