I usually don't post to questions like this but first google just ignores spammy backlinks.
Search engine rankings, relevance, and page authority are all factors for Google backlinking. The editorial value of your hyperlinks is also something Google considers in backlink quality. The value of high-quality backlinks to your site can't be overstated, especially if you want to rank well in search results
Backlinks to avoid?
Paid Links. Search engines look at your site's value based on how well it's been liked by other real and earned sites.
Backlinks in Press Releases That Are Not Newsworthy.
Low-Quality or Irrelevant Directory Links.
Low-Quality Forum Backlinks.
Domains with High Spam Score.
and to note that recently Google has been aware and watching purchasing expired domains with backlnks

Build Quality Backlinks:
3. Link Building Strategies: Develop a comprehensive link building strategy focusing on acquiring backlinks from authoritative and relevant websites within your industry.
Guest Blogging: Identify reputable websites in your niche that accept guest posts and contribute high-quality articles that provide value to their audience.
Broken Link Building: Find broken links on other websites within your niche and reach out to the site owners suggesting your content as a replacement.
Content Promotion: Actively promote your content through social media, email newsletters, and outreach campaigns to increase its visibility and attract natural backlinks.
4. Internal Linking:
Contextual Links: Incorporate internal links within your content to connect related pages on your website. This not only helps users navigate your site but also distributes link equity throughout your domain.
Anchor Text Optimization: Use descriptive anchor text that accurately represents the content of the linked page. Avoid generic phrases like "click here" and instead use keywords relevant to the linked page.
