What are not (necessarily) spammy backlinks
Some companies choose to disavow links, based on certain metrics or other features. Google itself doesn’t work this way. They assess the parties that are linking to your website based on relevance. That’s why excluding based only on metrics is a bad idea. We’re also not a big fan of metrics like the ‘spam score’ from MOZ or the ‘toxic link score’ from Semrush. Tools like these are often not that good at really seeing what spam is anyway. We would recommend not disavowing backlinks like the following:
- Links with a DA (domain authority) lower than 10
- Links with a high spam score in MOZ
- Links with a high toxic link score in Semrush

What are the risks of spammy backlinks?
The risks of spammy backlinks are quite small. In the past, the use of negative SEO was quite frequent. One of the main tactics to hurt the rankings and search engine visibility of competitors were, you guessed it, spammy links. This has caused Google to decide to just ignore spam and other negative types of SEO. So in a nutshell, the risks are very low.
