Expired domains with DR 20 and above

Originally the site was a network of Turkish online calculators (2019–2023), then it morphed into a suspicious Chinese resource with a typically spammy page title (2024–2025). The niche change is complete, and the final niche does not match the period of backlink profile growth.

The site was originally tied to the brand "Bioden" (likely a Korean product or company, judging by the page titles), and it consistently operated in that niche until early 2020. This was followed by a long stretch of empty page titles (2021–2022), and the final niche before the drop was a Chinese football betting site, typical gambling spam.

Throughout its history, the domain never had real content; page titles fluctuated between the domain name and "One moment, please...", indicating constant parking. No actual niche was ever established, and the site was never a live project.

Monothematic online casino Pin Up website in Azerbaijani. No niche changes recorded; all content is related to gambling.

The domain was originally used as an educational portal/LMS with a login page ("D-710AE1 - Login") from 2011 to 2016. After a long period of inactivity and a blank page, since February 2025 the domain has been taken over by Indonesian spam gambling (Togel).

The domain originally belonged to D-AA32ED (2009–2015) with periodic "Under Construction" placeholders. After 2021, the niche abruptly shifted to Japanese affiliate spam (diets, cosmetics), then to Chinese adult content. The niche change is radical and unrelated to the original link profile.

Originally (2007–2016) — a Japanese site, based on page titles, tied to historical subject matter (Ryoma Sakamoto, «龍馬»). In 2017–2018 — a period of uncertainty (empty page titles, just a domain). From 2019 to 2023 — an English-language site «Latest Beauty News» (beauty niche). In 2024 — a return to a Japanese title about Ryoma. In 2025 — «龍馬おすすめAV» (Japanese adult content). The final niche is adult, which completely diverges from the original historical niche that links were likely built for.

Originally (2001–2004) the site was dedicated to web design and development, then repeatedly changed direction: redirects, a developer's personal page, and since 2019 — entirely Japanese content, first about housing rentals, then outright spam (pharma, online casino/pachinko). The final niche (gambling) is completely irrelevant to the original one, which likely accumulated the backlinks.

History is unstable: in 2011–2016 the site existed as a minimal/placeholder page with page titles like "D-DD04D0.net | Urban", then in 2020–2022 it was used for SEO spam on bearings (NSK, angular contact ball bearings), after which in 2023 it switched to the Chinese online casino "澳洲幸运10", and by 2025 it went into domain parking/a domain-for-sale page.

The domain had no meaningful content for a long period (2010–2018), with empty page titles and load errors. In 2021, a Chinese-language site appeared related to sports betting (乐鱼买球). Since 2025, the niche shifted to explicit porn spam with keyword-stuffed titles.

For most of its history, the domain had no clear niche (page titles like "D-D20B18.net", "Home", or empty), and only briefly in 2021–2022 did it exist as a news portal for the Dominican Republic, after which it degraded again. The main link profile is unrelated to this niche and was likely built up during spam periods.

Originally the site was dedicated to hotels near stadiums for the 2018 FIFA World Cup in Russia, then the niche was updated to the 2022 FIFA World Cup in Qatar. The shift was logical, but the final niche is now outdated (the event has passed).

Originally (2003–2009) a Japanese site about web hosting and domains, then (2010–2017) a page titled "postman" (likely a technical service or placeholder), followed by (2018–2023) blank pages with no title, and in 2024 — a sharp shift to Chinese spam content (porn/casino). The final niche is completely irrelevant to the original.

Originally a personal blog/site by Jiri Barton (D-E62E86), live from 2008 to ~2014. Final niche before the drop — online casino/gambling (SANS189), which is completely irrelevant to the original link profile.

From 2004 to 2018, the site consistently served as the website for a French hotel (D-6F7EBB, Saint-Germain-des-Prés). In 2021, the niche abruptly shifted to casino/slots, after which the domain became empty/parked.

The site has been exclusively in the adult niche (hardcore) throughout its history. Initially (2008–2019) it was a static doorway page with the page title “D-38409E,” then (from 2020) it was relaunched as, likely, a German-language aggregator/affiliate site with the title changed to “Private D-38409E als Livestream oder Download ansehen.” No niche change.

Originally the site was related to knitting (2006–2007, page title "D-4E5C73"), then for many years (2007–2024) it sat in a parked/empty state, and in 2025 it abruptly turned into a spammy doorway page for the Vietnamese online casino QH88.

Originally (2009–2021) the site steadily operated in the UK dissertation help/writing service niche. From late 2022 the domain abruptly switched to pharmaceutical product sales (Norwegian spam about Viagra), then to Indonesian spam and gambling (slots).

The domain originally belonged to the "D-69B10E" PHP library project, related to RSS feed parsing. Since 2021, after parking at OVH, the niche has completely shifted to spam/adult (porn resources in Chinese and English),

The only recorded meaningful page title, "D-332978" (2024-04), points to a portfolio site or agency. However, for most of its history the domain either redirected or served blank pages, so no stable niche can be established.
