Expired domain catalog

From 2002 to 2019, the domain was a static business card site "Welcome to 'D-53DB00..." (likely a guest house or vacation rental). In 2021, the niche abruptly shifted to a Chinese sports streaming site "人人体育直播视频" (sports broadcasts), after which the domain went into a 301 redirect.

Originally a Japanese site about servers (2004-2007). From 2008 it turned into a spam doorway with page titles stuffed with keywords (car insurance, cash advance, debt consolidation, Gucci). In 2019-2021 — an empty WordPress blog and a Chinese gambling site. Complete chaos and niche changes.

The domain started as a dating/escort site (fuzoku), then shifted to adult video, casino/gambling, adult manga, a personal blog, and finally adult doujinshi. Multiple niche changes; the final niche (adult doujinshi) does not match the niche that likely built most of the backlinks (adult/casino).

Initially and for most of its life (2021–2023), the site was a stable resource for free engineering books in PDF, which matches the domain name. In 2023, the niche shifted to a vague "Highly Rated Engineering Books," after which the site stopped being substantive and turned into a technical placeholder.

Originally (2011–2016) — the site of the French government digital agency for the Correze department. Then parked (2019–2021), after which the domain was used for Japanese doorway pages about cosmetics/shampoos (2021–2022) and Chinese porn spam (2023). The final niche is completely irrelevant to the original one and the link profile.

The site had a consistent niche of 'D-CA5F52' (likely a culinary blog) during 2019–2022, but before and after that period it used unnatural redirects to an archived copy of itself.

From 2006 to 2023, the domain consistently hosted a D-16A470 site ('D-16A470') with no signs of niche change. In 2024–2025, content abruptly shifted to Chinese spam doorway pages with porn keywords, marking a drastic niche change that is irrelevant to the original link profile.

Originally the domain belonged to a legitimate web studio/marketing company (2006–2014: “D-4DA59C — Professional Multimedia Development”, “Web Design, Development and Marketing Company”). Then the niche changed multiple times: a “Coming Soon” placeholder and default WordPress (2015–2018), casino content “sic bo dice game” (2018–2019), a product slogan “we add charm to your product” (2021–2022), Chinese lottery spam and “Car Prices in India” (2023–2024), after which an empty title “D-4DA59C” remained. The final niche does not match the original one, which likely received the main backlink profile.

Originally (2019–2020) the site was dedicated to unblocking corporate accounts under Federal Law No. 115-FZ; in 2021 it switched to content about the Schengen Area, and by 2023 — to Korean gambling/먹튀 spam, after which it remained empty/without a title.

From 2007 to 2010, the domain consistently operated as a news site focused on Vedantic and Sri Vaishnava philosophy (Hinduism). After 2011, the content disappeared, and the site shifted to constant redirects or blank pages, with the niche no longer maintained.

Multiple changes: initial (1998, likely a Swedish site), then a long period of pharma spam (2002–2009, 'No Prescription Required Drugs', 'Buy Soma', 'vicodin'), an attempt to switch to sports news (2018, FIFA World Cup), later — gambling spam (2025, Thai casino) and frequent empty/parked pages. The final niche before the last drop does not match the period of backlink growth (pharma spam).

No niche throughout its entire history. The site was never a full-fledged content project; it existed as an empty directory ("Index of /") or a page with no title.

The domain was consistently used as an adult site from 2015 through early 2025 (keywords: granny, MILF, mature). In 2025, the niche abruptly shifted to online casino/slots (MW68), which is completely irrelevant to the historical link profile.

Originally (2013–2017) a stable Spanish travel blog. Then a series of redirects and parking, and in July 2024 an Indonesian online casino site ("Sunmory33"). In 2025–2026 a Japanese travel blog appeared. The niche changed: travel → gambling → travel.

Originally the site of digital agency "D-BBF8D8" (2009–2010), then a long period of domain parking (2015), after which it completely switched to a Japanese adult site (2015–2018). Later — a server test page, a "Spam Check" placeholder, and redirects to unknown resources. The niche that built the backlink profile is highly likely related to adult content, which does not match the original profile.

The domain initially (2004–2007) had empty page titles; from 2012–2014 the title displayed "D-5DAC1F," indicating a travel niche. After 2015, no content was present (empty titles/parking), and the final niche before the drop was not expressed.

Originally a Portuguese-language site about digital communications and network initiatives (2011–2021; page titles "D-A5020C – Ações em rede!", "#D-A5020C – Comunicação Digital"). Since late 2023 — a Vietnamese pirate football streaming site (Xoilactv/Xoilac), so the final niche is completely unrelated to the original one and the link profile.

Initially the domain was used for redirects to unknown resources; since 2019 it consistently operated as a Chinese gambling site (万搏体育); in 2021 it switched to an automotive niche (“Ymlp Automotive”), after which it declined and went into domain parking. The main link profile was formed during the gambling period and is irrelevant to the automotive niche.

Originally (2000-2005) a stable site about D-23DBE3 and mind control. From 2006 onward, chaotic topic changes began (spam doorway, Japanese dentistry, Chinese casino, football jerseys), which completely devalues the original link profile.

The domain went through extreme niche changes. For a long time (2004–2015) it existed as a personal portal/blog D-0825A4 Network, then (2016–2017) tried to become a "Women's Firearm Blog Center", after which it turned into casino content in Chinese (百利宫), and now it has ended up as a spam doorway selling football jerseys in Spanish.
