31-60%: These sites should be approached with caution. While not necessarily harmful, links from sites with a spam score in this range may not provide strong SEO value.
61-100%: High risk of being considered spammy. It’s advisable to avoid backlinks from sites with a spam score in this range, as they could hurt your SEO rankings or lead to penalties.
