Expired domains with DR 30 and above

Originally a Chinese online jewelry store, then repurposed as a WeChat marketing platform, and after the drop it was used for online casinos (J9, w66).

From 2010 to 2020, the domain hosted a legitimate educational math site ("D-3DE302"). In 2020-2021, page titles went blank, and from 2022 onward, the domain turned into a casino farm (Chinese casino brands, porn spam in page titles, etc.).

The domain started as a Turkish religious sacrifice service, then pivoted to lingerie delivery, later became an e-commerce site, and after a long period of inactivity and parking was taken over by Chinese and Indonesian gambling sites. The final niche is outright spam casino.

From 2016 to 2021, the domain was consistently used as a local business site selling trophies and awards (Hi Desert Trophy & Awards). In 2024, the niche radically shifted to a Chinese online casino site (开云/Kaiyun), then to sports betting (千亿体育).

Throughout its active life (2024-07 to 2025-02), the site was dedicated to the topic of "D-59A806" with no niche change.

Multiple niche changes: empty domain parking (2018), spam site on Chinese sports betting (2022–2023), mysterious redirects to D-E5C7D2.org (2023–2024), a short period of content about gemstones (2024), and sports betting again (2025–2026).

Initially (July 2024) — gambling (lotteries, jackpots). Since September 2024 — only technical placeholders saying 'One moment, please...' and 301 redirects to unknown resources, with no real content since.

From 2007 to 2020, the site consistently served as the official website of the Persian company "Negar" (وب‌سایت رسمی شرکت نگار). Starting in mid-2024, after a series of redirects, the site drastically changed its niche to an English-language resource with the generic title "All About Everything," which by the end of 2024 had turned into an online games site ("Games Online for free").

Originally a domain about purebred cats (D-D64FAF.net, 2000–2017), abruptly switched to escort/tantra massage in 2020, and after 2022 — unstable redirects and technical placeholders.

Originally (2022–2023) the domain was in English in the business valuation software / data room niche, then from 2024 it abruptly switched to a Korean site about karaoke in Suwon (수원가라오케). The niche change is drastic and unrelated to the original.

The site was originally related to Photoshop (possibly warez/free downloads), then abruptly switched to gambling (casino/toto), and later moved to design tutorials. The final niche (design) does not match the period when the bulk of the backlink profile was likely built (gambling/Photoshop).

Originally (2004–2014) the site was in the career/recruitment niche (D-B87677, job search, employment), but since 2015 the niche has changed multiple times: Japanese spam content (2015), Cambodian job listings (2019), Korean content about investing in Cambodia (2020–2023), then Thai/Singaporean content about tea (2023–2025). The final niche does not match the original career niche, which is likely what the backlinks were built for.

Originally the site was dedicated to American Indoor Football. In the final stage, in August 2024, it abruptly switched to a spam portal for online casinos (slots) with an Asian slant ("NAGATOP: Situs Slot Gacor...").

The domain was originally used for a real estate site ("D-3F1E13"). In 2025, the niche drastically shifted to Chinese gambling spam ("球友会-球友会（中国）"). The link profile is highly likely irrelevant to the final gambling niche, which, however, is not the main issue.

Originally (2009-2010) the domain was used for a Chinese online game site ("woool" — Legend of Blood), then in 2016 it switched to private server clones. The final niche before the last redirect was hardcore adult content (Asian, incest-like terms), which is a complete mismatch with the gaming link profile.

Stable niche in gas sensors and laser spectroscopy (D-12D2AA Gas Sensing) from 2009 to 2019. Title changes do not indicate a niche change, but rather rebranding or SEO optimization.

The site existed for a long time as a coffee-related website, but after the drop it turned into a Chinese online casino (likely phishing or expired domain flipping).

Site history unknown — only one snapshot (July 2025) is recorded in the Wayback Machine, showing a 301 redirect to an unknown domain. It is impossible to determine what niche the site served before or whether it was a live resource.

The domain started with English-language content (2018–2019), then went through long periods of redirects and downtime, and was finally switched to Chinese content (PG电子 — gambling/casino) starting 2025-07. The complete change in niche and language indicates resale or repurposing for spam.

From 2002 to 2017, the site consistently operated as a niche resource about Bed and Breakfast / Privatzimmer in Munich (German content, page titles unchanged). Since 2021, the domain shifted to Chinese content (公司), then Vietnamese (Trang chủ), and finally to an empty/irrelevant title "D-C976E3". A complete niche change in the later period of operation.
