Expired domains in industry and equipment

Originally (2003-2016) a Japanese site selling musical instruments (pianos, saxophones, DJ equipment). In 2022, the niche shifted to landing page creation (lp制作), and in 2023-2024 the domain was used for Asian porn spam with keyword stuffing in page titles.

Multiple niche changes: from a Russian-language personal blog/cooking (2010–2015) to a Chinese online casino (2018–2020), then to animal feed pelletizing equipment (2022–2024), and finally to an Indonesian gambling site (2024). The final niche (casino) is completely irrelevant to the original link profile.

A German-language site about pond pump testing (D-C7D6A6), but the domain is a typo-squatter (D-C7D6A6.com instead of D-C7D6A6.com) and throughout its history alternated between its own content and redirects to the original domain D-C7D6A6.com.

Originally (2006–2018) the site of a Chinese manufacturer of electronic components (microwave devices, filters, amplifiers). Since 2019, the niche shifted to casino spam, then to porn spam, which is completely irrelevant to the original link profile.

Initially a site for a Chinese company selling industrial equipment (2013-2016), then a sharp shift to a spam doorway with gambling and casino content (2017-2020).

Originally the site of the Federation of Chambers of Commerce and Industry of Sri Lanka (D-F7718E) from 1999 to 2022, with a gap of a blank title from 2011 to 2014. After the drop in 2023 — gambling (FB Sports) and explicit adult content.

Multiple niche changes: from unreadable spam (2012-2013) to a Chinese gossip/entertainment site (2013), then a long period of inactivity/redirects, followed by a Chinese industrial site focused on gas equipment (2017-2022), and finally a transition to a private investigator site (2024).

Stable PCB manufacturing niche (Deshine), no niche change throughout the entire recorded history.

The domain started as a local Italian portal (Reggio Emilia), then had long redirects (2018-2019), after which it sharply switched to Chinese spam content (boiler manufacturing, then casino/gambling). The final theme completely mismatches the original and is clearly spam-oriented.

Originally (2002–2004) the site of a Chinese hardware manufacturer (五金制品). The niche changed multiple times afterward: in 2011–2012 it was used for a spam page for an online casino (gambling), in 2014 it was taken over for a wedding invitation, and in 2021–2022 it turned into a doorway page with adult content and links to online streaming sites.

Final niche — Iranian metallurgical/manufacturing company ("حدید فلز سبلان"), but it only appears in March 2025. Before that (2023–2024), the domain either sat on 301 redirects (including to unknown addresses) or served blank pages with no page title, which makes it impossible to confirm that the old link profile matches the current niche.

Stable niche of lighting and chandelier manufacturing (OEM/ODM) in China with no niche changes throughout its history.

Originally, the site was dedicated to wooden product manufacturing (Thùng Gỗ Phạm Gia) in Vietnamese. In 2024, the content disappeared, replaced by an empty index page, and in 2025 the domain transitioned to a parking/redirect state with a "One moment, please..." placeholder.

From 2016 to 2019, the domain consistently hosted the site of a Chinese manufacturer of automatic screwdrivers/machines (顺科自动化). In 2021, the niche abruptly shifted to gambling/casino (澳门太阳网站, 澳门十大电子游戏平台). After 2023, empty page titles (parking/blank pages) were observed, with a brief return of the company name in 2025-12 and emptiness again in 2026-01.

Originally a Thai floating market site (2012–2014), then a long period of redirects and domain parking; in 2022–2025 it fully shifted to hydraulic pumps, and in late 2025 explicit porn spam appeared.

From 2013 to 2021, a stable video content production site. After a long period of 301 redirects (2021–2024), the domain was dropped and now hosts a Chinese sports and gaming service unrelated to the original niche.

Originally the site of D-AFE4F6 Company, Inc. (1999-2009), then, after redirects, became the site of Linear LLC (access and security equipment, 2010-2014). In 2022, a Chinese-language site appeared (gambling/casino), and in 2023 — marketing content. The final niche before the drop was an empty page with no content.

Originally a site about Smokie band concerts (2018–2019), then switched themes twice to industrial equipment (flotation cell) and mattresses, with an intermediate return to Smokie. The final theme (mattresses) does not match the original, which is likely what the links were built for.

From 2008 to 2022 the site consistently existed as an agritourism (country hotel) site in Bologna. In 2023 there was a sharp, drastic niche change to industrial (crushing plants, copper production), which completely does not match the original link profile.

From 2013 to 2021, the domain hosted a static site with the title "Home" (likely a personal site/portfolio for D-8F9C46). In May 2022, the theme abruptly changed to industrial hoses with a keyword-stuffed title "High pressure hose|hydraulic hose|industrial Hose|hose assem", after which the domain dropped.
