How spam score will be calculated for the domain without any content or backlinks?

[vtmoz]

Hi Moz team,

I have noticed that one of our old domain has high spam score of 9. This has been redirected to our domain around 2 years back. I can see that old domain doesn't have any back links. Then how come the spam score have been calculated for this? If there is any metric for this, we just wanna remove redirecting this spammy old domain to our domain. Please clarify.

Thanks

Hey there!

Spam Score doesn't update with the same frequency as the rest of the data in Open Site Explorer, so it's entirely possible that the score you're seeing for your old domain is outdated and no longer accurate. It sounds like it's been long enough that the backlink info for that site has fallen back out of our index — linking data is only stored for around 180 days — but the Spam Score hasn't been updated yet. 
​
I would expect to see the Spam Score for the old domain change after that metric updates again. Unfortunately, I don't know when that will be — I don't have an ETA for when Spam Score will be updated next. Sorry about that!
