No Backlinks But Spam is 50%

The domain has Zero Backlinks and No posts… But Spam is 50%…
When I bought this domain there is no spam…
I just created a wordpress site and kept it empty for 3 months… Now the spam is built over 50% even there is no single backlink
It doesn’t make sense… How Moz is calculating this spam score…
What u people say…? Do I start write content on this domain now… Guide me please

Anyone please tell should I start blog on this spam domain or not…?

It’s better to leave the domain and start with another fresh domain name.

When I checked with some people they said Moz spam is due to the same kind of domains in the past got spam before… thats why its showing more than 50% score… Also, they said spam will go after you write content…
