@lorosing I agree with you, the spam score from my site was up at 5, after I employed a cheap SEO "EXPERT" to improve my ranking. I'm in the car insurance/accident business, so there's huge competition for ranking. These guys just use rubbish links from rubbish sites and the spam rating just went through the roof, and I wasn't ranking for any keywords related to car accidents at all.
Now though, after much pain and headache, I got all the dodgy links removed and disavowed. It took a few month before the spam rating fell after that, but it was worth it in the end. So if you've disavowed them then just wait and you should see your spam rating drop back. Otherwise, you may have to just change your domain name!
