Expired domain catalog

Originally a site about D-0A2F44 County in China with news content, stable from 2016 to 2023. In 2025–2026, the niche shifted to spam (pirated streaming "cakhiatvrrcc") and parked pages.

The domain started as a scientific resource for systems biology (ERATO Systems Biology Workbench, SBML and SBW) in 2002–2005. Later the niche changed multiple times: there were periods of empty page titles, redirects, then "Informative news" (2021–2022), and in 2024–2025 the site turned into adult content with Chinese keyword-stuffing page titles.

Originally a blog on large-scale Agile development (2013-2015). The niche was then lost (empty page titles from 2016 to 2022), after which the domain was hijacked and turned into a Thai gambling portal (GVA88) in 2025-2026.

From 2015 to mid-2025, the domain consistently represented a site for an organization advocating for payments on Peruvian agrarian bonds (finance/activism). In late 2025 to early 2026, the niche abruptly shifted to gambling/casino (page titles TAJIR5000).

In 2012–2018 the domain represented a Chinese IT/software company (盐城海派科技 / 徐州海派科技), then the niche shifted to 'internet + agriculture + finance', and since 2021 the domain has been a casino site, since 2022 — a porn/spam doorway. The final niche does not match the stage of backlink profile accumulation.

Multiple changes: domain sale (2016) → empty placeholder (2017) → porn spam (2021–2023) → Douyin follower inflation service (2025–2026). Final niche is gray (inflation), which does not match the likely backlink profile acquired during the porn period.

From 2005 to early 2024, the site consistently existed in French within the electric heating niche (radiators, energy-efficient heating). In 2024, the niche abruptly shifted to a Japanese blog, then to other Japanese content unrelated to the original niche.

Originally a Chinese travel blog (2021–2022), then a sharp pivot to a spam doorway with pirated movies and adult content (2026).

Originally (2006-2008) the domain represented the company "D-7C3FE2" (likely IT services). After a long period of inactivity and domain parking (2012-2016), the niche recovered as IT support and web development (2018-2022). The final niche before the drop was a Chinese online casino/gambling ("Kaiyun", "必一").

The history shows a series of shifts from an empty/non-working site to Asian spam (gambling, casinos), then to adult/pirated content (adult web player), and finally to a Thai online casino. Throughout the entire period, there was never a legitimate, "white-hat" niche.

Originally an English-language portfolio of photographer/artist D-88044A (2012–2017). After the drop, the niche radically shifted to Japanese spam (2018–2019: debit cards; 2022: market research), then the domain was used as a redirect layer (302→unknown).

Originally the official website of the Siak Regency Education Office (Indonesia); the latest snapshot shows a sharp shift to gambling spam (Togel Sidney).

Originally (2019-2022) the site was dedicated to marketing consulting for small and medium-sized businesses (SMEs), then abruptly switched to a Japanese site about pocket Wi-Fi router rentals. The final niche is completely irrelevant to the original one and, in all likelihood, irrelevant to the backlink profile.

The domain was originally used for a niche related to "D-D43B52" (likely energy news or a Caspian European Club project, based on early data), but between 2022 and 2025 it underwent a radical shift to content for the Vietnamese online casino "Thabet".

Initially a Chinese electromechanical equipment company site (2009-2010), then a long period (2014-2016) used for casino/gambling, followed by redirects and a final switch to the brand "安博" (2025-2026).

In 2016, the domain was used as a spam store for cheap shoes/counterfeits ("Cheap Jordans For Sale", "Cheap Air Max Shoes", "Lebron James Shoes", etc.). Then from 2017 to 2021 it remained essentially empty/parked (empty page titles, fetch_failed), and in 2022–2024 it intermittently showed the title "D-5AE6A3" with no confirmed content. The final niche is not established and does not match the historical link profile, which is almost certainly tied to the old shoe spam.

The niche history is unclear: from 2021 to 2024, pages mostly returned 200 OK with an empty page title (likely parking, a placeholder, or empty JS content), and by July 2025 an obvious spam title appeared: «新奥门六开奖号码今晚开奖结果-无弹窗广告的免费小说阅读网站» (Macau lottery/casino + free online novels). The link profile was likely built on empty/parked content and has no relevant topical core.

Originally (2015–2020) — a Chinese pirate movie site (mentions of Qvod, Xigua, Baidu Player), then after a period of redirects and downtime (2021–2023), since 2025 — an adult site with explicit porn content.

Unknown — the Wayback Machine contains no snapshots, making it impossible to analyze the niche or its stability.

From 2014 to 2017, the domain looked like a collectibles site/brand (page title "D-81DDAB"). After parking in 2019 and resumption in 2020, the niche remained the same — "Collectibles for Sale", with no clear shift to an unrelated niche recorded.
