How to remove old spam links?

Question

Search Engine Optimization

Good day.
There is a new blog, we fill it only with our content (we write it ourselves). There are no links to external resources. But spamming is very high.

Checked the history of the domain name. The domain was active in the period 2007-2009, and then from 2013 to today we are the owners.
How to remove spam links? I can’t even find them, there is no site in the search, they haven’t applied for indexing yet.

Answer 1

So the data has probably not been updated yet, for example, you have 9 links from the main one. Still sometimes counters are considered as links
