Expired domains with DR 20 and above

Originally a flower-themed site, «嘉定区鲜花网» (Jiading Flower Website), existed since 2023. In January 2025, there was a sharp shift to blatant porn spam with keyword stuffing, then in August 2025 the niche returned to flowers, followed by a 302 redirect to an unknown resource in December 2025, and in January 2026 it was 'flowers' again. The final niche matches the original, but the link profile is highly likely contaminated with irrelevant and spammy links acquired during the porn content period.

Initially, the domain had no content (long 301 redirects to the www version), then in February 2025, spam content with porn keywords in Chinese was recorded, and since August 2025, the topic has changed to 'fitness training in Macau'. There is a sharp irrelevant topic change.

The domain started with empty pages and redirects, then briefly (summer 2019) had a sports jersey niche, but quickly switched to online slots in Indonesian, and later to Asian adult content with heavy keyword stuffing. The niche changed at least three times, with the final one before the last redirect being spam porn.

The site consistently operated in the niche of sports predictions and football betting (mix parlay, over/under) from 2025 to 2026. The niche did not change, but it is inherently a high-risk YMYL niche (gambling).

Initially an "Index of /" page (March 2024), then from May to July 2024 — a slot game provider site (gambling, page title "D-540010 : Game Provider Online Terbesar"), followed by empty page titles — the niche did not change, but the short active period and niche are typical of spam projects.

No niche. Throughout its history, the domain has shown no content other than an auction page and empty page titles.

The domain was parked for a long time; in 2019–2021 it hosted a site with the page title «D-E994CF» (likely in the business analytics niche). No niche changes have been recorded.

Cannot be determined due to lack of Wayback Machine data.

The domain has changed themes multiple times: first an English-language 'D-68C462' (2002–2006), then a Chinese resort/spa (2008–2012) with some lottery predictions mixed in, after 2019 — empty titles and adult spam (2024). The final theme before expiration was an explicit porn doorway with no relation to the original link profile.

The domain has not demonstrated a clear niche throughout its history. Snapshots contain only generic titles ("D-B592ED.io", "Loading...") with no indication of a specific niche or content. It is impossible to determine which niche built the main backlink profile (272-422 backlinks).

Originally a site about professional road cycling (2016-2017), then turned into an empty WordPress blog(2017-2019), after which it moved to Asian gambling/betting(2025) with the latest redirect.

The site was originally dedicated to D-1C9264 systems and maintained this niche throughout its active life. In recent years (since 2022), the content disappeared, and the site now shows empty or technical page titles.

From 2011 to 2016 — a stable website for a sign and design company (Art Plus Signs & Designs). In 2017, a brief episode of switching to a hosting article, then a return to the original niche. After 2021 — signs of domain parking, empty page titles, and in 2025 — takeover by a Chinese gambling site (D-C3DBED.com华体会中国).

Originally (2018–2019) the site was dedicated to cryptocurrencies (“D-AEEA70 – Insight into future”), then after a period of downtime and a suspicious redirect it switched to Chinese gambling (c7体育) and other spam landing pages. Final niche is spam, which does not match the link profile niche.

The domain originally belonged to the food company Pioneer Food (2008–2014), then went through a long period of redirects (2015–2025), and in 2025 became a Chinese gambling site (好博 — online casino).

From 2008 to 2021, the domain consistently operated as the website for D-35DEBF Service. Then a long period of inactivity/parking (2023–2024), and from 2024 to 2025 the domain completely switched to online gambling and changed brands two or three times (华亿体育, 好博, MKsports), with content in Chinese and Bengali. The final niche has nothing in common with the original one.

Consistently gambling/casino site in Portuguese, no niche changes.

For the entire documented period (July 2025 – June 2026), the domain was used as a one-page affiliate site for an online casino in Portuguese, with no niche changes.

Originally a Thai online anime streaming portal, consistently active in that niche from March to December 2022. Starting in early 2023, the content disappeared and the site turned into a technical placeholder with no defined niche.

Korean link aggregator site (주소모음/링크모음) — «주소콕», niche unchanged over the observed period; it's a typical link collection / link directory, often used to redirect to adult/gambling/streaming resources.
