Expired .com domains in industry and equipment

Originally (2018–2019) — the site of a Chinese industrial flooring company, Jiangxi Yiqiao Flooring Engineering Co., Ltd. In 2020 — an empty page title (possibly parked or a half-dead site), in 2021 — a drastic shift to gambling/betting niche 'm6米乐'. Later the domain serves 301 redirects, in 2025 — to an unknown address.

Domain was a stable sign and T-shirt printing company site from 2011 to 2023 (Signs & Shirts). In 2025, after a gap, the domain was taken over by a Chinese spam site about gambling (新澳彩).

The domain spent its early years in redirects and with empty titles. From 2018 to 2022 it steadily developed in the "D-DC8D47" niche (parts washing equipment). After the drop, in 2025–2026, the theme radically changed to Chinese spam content (titles "mk官方网站-mk(中国)").

Originally (2021) the domain belonged to a Chinese building materials company '甘肃鑫怡林达装修材料有限公司'; in 2025 the topic radically changed to an online casino/gambling brand '南宫·NG28(China)'. The final topic does not match the original one, for which the link profile was likely built.

Originally the site of a Chinese company selling telecom equipment, then a drastic switch to gambling (brand BOB) before the final drop.

From 2018 to 2022, the domain consistently hosted a site about industrial washing machines (manufacturer Feilong Machinery). In 2025, the niche abruptly shifted to gambling (dealers, online casino Kaiyun) – the link profile is irrelevant to the new spam purpose.

Originally a French site of unclear niche ("Les D-86EAF1"), then a Japanese bag store, a Japanese job-change site, a Chinese industrial site, a phishing site for a casino brand, and finally a Canadian online casino. Complete chaos, final niche — casino.

Originally the site was related to manufacturing/assembly (page title "D-4B7BBB"), but since 2023 the niche has disappeared (empty page titles), and the domain has turned into a "redirect placeholder" with no content.

Originally a Chinese pump manufacturer's site (2012-2015), then switched to a Chinese novel site (2016), after which it degraded into Asian porn spam and a casino farm (2022-2025).

The domain started as a site for a Chinese manufacturer/seller of analytical equipment — ROHS analyzers, XRF spectrometers, instruments for metal and food analysis. Since 2024, the niche has radically shifted to VPN/accelerators: first "蚂蚁加速器", then "毒舌加速器", with explicit mentions of "cracked/free" versions.

Originally (2005–2009) the site of a professional marketing and media research D-5B4BF5, then long redirects and since 2021 a complete niche change to Chinese spam (mechanical plant, online casino, escort services).

Originally a CNC/machine tool resource: from 2006–2007 it was Haas Factory Outlet, and from 2011 to 2020 it was NYMAT Machine Tool Corporation (same industry — Haas machines). Then from 2022 to 2024 it had empty/blank pages, and in 2025 it was repurposed into a Chinese-language site 'ML.COM-米兰(中国)', likely casino/spam — completely irrelevant to the original link profile.

Originally the site was dedicated to the product "D-61394C" (audio processing); the niche was stable from 2011 to 2018. Since 2019 the domain moved to parking/for-sale status and finally expired in 2024.

Originally a Chinese industrial company site (heavy machinery, chemical equipment) in 2010–2020, then in 2022–2023 — blatant adult spam content, after 2025 — small business sites (doors, hotel supplies). Multiple niche changes, final niche unrelated to the period of backlink growth.

Originally, the site was dedicated to selling and reviewing fire safety equipment for the Vietnamese market. No niche shift was recorded; however, since January 2020, live content disappeared, and the page existed without a page title.

Originally a Chinese SEO/web studio site (2021), then a sharp pivot to a printing equipment manufacturer (2025), followed by the final niche — gambling (casino/sports betting, 2025-2026).

From 2011 to 2021, the domain was consistently used as a Spanish-language news portal (a Dominican digital periodical). In 2023, the niche abruptly shifted to a Chinese commercial site (pump equipment), and in 2025, to a gaming/casino resource.

Initially, the site represented a company manufacturing household goods (2025-06), then abruptly switched to an online casino/gambling login page (2025-11).

Originally (2004–2014) a stable site selling medical equipment. After a long period of redirects (2015–2018), the domain was hijacked and used for doorway pages/spam with multiple niche changes: Japanese watches (2021), hockey gear (2021), and Chinese sports betting (2024–2025). The niche that built the link profile (medical) does not match the final one at all.

The site started as a resource for an industrial equipment company (mixers, nozzles) in Nanjing, later changed ownership to a similar company in Nantong, and since mid-2024 has turned into porn spam with aggressive keyword stuffing in page titles.
