Expired .net domains with a past

From 2005 to 2013, the domain served 302 redirects to unknown addresses; from 2013 to 2018, it showed placeholders/parking (page titles "D-82B34C.net", "The Leading Tool Site on the Net", and empty titles). Only in 2025 did a Japanese site about free tools appear ("Free tools | 無料でできることを色々解説"). No stable niche existed before 2025.

From 2012 to 2021, the domain consistently hosted the "National Demonstration Test Catchment Network" site — environmental/water niche. In 2022, the niche abruptly shifted to gambling/casino ("Gambling Demon", "Koinslot Link Gacor"), then to e-commerce "Shop - 1-Week Deals", and again to casino spam. The final niche does not match the original one, which is likely what the links were built for.

Originally a UN site dedicated to urban water management in African cities (2000–2004), then became a UNWAC placeholder (2005–2006), after which the niche changed multiple times: to a vacation blog (2015–2017), to hydraulic pumps (2022–2023), and parking (2020–2021). The final niche does not match the original one, which accounted for the bulk of the link profile.

Multiple changes of niche and owners. Started as a telecommunications company site ("D-01645A Communications"), then switched to "All Spanish Radio", spent a long time parked or on empty placeholders, then briefly became a news blog. The final niche before the drop was veterinary technology in Spanish, which does not match the historical link profile.

Originally a personal portfolio for a graphic/web designer (2011–2020), then a sharp pivot to a Chinese construction company site (2021), and finally Chinese casino spam (2022).

From 2008 to 2017 — a social network for Oracle professionals (stable niche). Since 2024 — gambling/casino (slots, gambling spam).

Stable Japanese niche related to mental training, child development, seminars, and services of the company «原動力». No niche changes observed throughout its history; the site remained in one informational field.

Originally (2010–2018) a Russian-language site on esotericism/wish fulfillment. Then a long period of instability (2018–2025), after which the domain was repurposed for gambling (2025), and later content from the old niche reappeared in English (possibly an attempt at masking).

Originally a Japanese site (likely local, tied to the city of Yokohama — judging by the kanji in the Shift-JIS mojibake), consistently live from 2006 to 2023. In 2025, the niche radically shifted to Asian porn spam (keyword-stuffed page title).

Originally the site was about Asian girls, but quickly shifted to adult dating ("Ich D-6D27CA - Sex gesucht"), which later evolved into "Ficksuche" and "Fickdates". The niche has been stable within adult dating since 2009.

Originally (2010–2012) a Japanese tech/advice blog («便利な機能をできるだけ無駄なく使いこなす»), from 2014 fully switched to a spammy AV-industry recruitment site (adult content, «AVプロダクションＡＶ求人»), which remained until 2020.

The site has always been dedicated to escort services and "sex for money" in Germany. The niche has remained stable throughout its history, except for technical glitches and one episode involving the sale of the domain.

The domain existed for a long time (2019–2023) as the "Sub Rosa" site with no clear commercial niche, then in 2023 it moved to a parking page, and in 2024 it was taken over for casino content (Vavada casino) followed by registration expiration.

Historically RC cars (2003–2008), then placeholder/parking, in 2018–2020 a Thai site about choosing radio-controlled models, from 2022 gambling, from 2025 adult spam.

Initially an academic project about sports and disability research in Japan. In November 2023, a sharp pivot to Chinese and Thai gambling (lotteries, slots), followed by parking and default nginx pages.

The sole and consistent niche throughout its entire history (2020–2024) is adult/porn (Granny/Gilf/Mature). No niche changes were ever recorded.

Originally D-92BECC (2001), then a sharp shift to unrelated content 'From Bar to Bear' (2002–2007), then back to D-92BECC with a personal angle (2011–2016). The final niche formally matches the domain name, but historical instability reduces trust.

Originally (2011–2012) the domain hosted the e-commerce service "D-C1BBBB"; after long redirects (2013–2021) the niche shifted to Chinese spam (first adult, then casino), completely different from the original.

The niche history is unstable: an early German-language project "Gepi_de" (2004–2005), then a long period of domain parking/sale (2011–2018), from 2019 to 2025 — an Arabic content project "عجيب وغريب" ("Strange and Amazing"), and in 2025 — a Spanish-language "OTTIS Comunicaciones Internet Sano" and a placeholder page "One moment, please...". The final niche does not match the Arabic period, which likely built up the bulk of the backlinks.

Originally (2011–2012) — a stable personal blog by Christopher Lawes. After a long period of inactivity, the domain returned by 2022 as a Thai gambling/slot site (PG slots). The niche change is radical: from a personal blog to an online casino.
