Expired .com domains in industry and equipment

Originally a supplier site for mechanical seals and pumps (2022), repurposed in 2024 into the Indonesian gambling casino "PECAH5000" — a sharp pivot to spam niche.

Originally an Indian manufacturer of industrial equipment (conveyors, crushers, gate valves) in 2017–2019. In 2020 and 2025, the domain was hijacked for Chinese gambling spam, with restoration to the original niche in between. The final state before the drop — again spam casino/betting content.

The original site was a Chinese road equipment manufacturing company (2016–2017), then switched to a betting site («365足球网站|365体育最新», 2018) and later to a pirated adult content app («旧里番app», 2021). The link profile was likely built for the early road niche and is irrelevant to the final spam content.

Originally a Chinese sanitary ware manufacturer's site (2013–2021), then abruptly switched to a movie site '198电影网' (2021–2022), and after a period of inactivity, a household tips site '秋霞生活常识网' (2023–2024). The final niche does not align with the period when the main backlink profile was built.

The domain was originally used in the mining industry and investment niche (2013–2016, 2017–2018), but then changed niches several times: reggae music (2016), a Chinese hotel (2023–2025), gaming account rentals (2025–2026), and finally a Chinese site of questionable content. The final niche is completely irrelevant to the original.

Originally (2017–2019) a narrow industrial niche — an air pump manufacturer. From May 2019 the site went idle/default, and from April 2020 it fully switched to betting/gambling (bet, ayx). Final niche — online casino.

Multiple niche changes: from undefined (D-104AD1, HOME) to gambling (2020), then to educational equipment (2021), then to a food company (2023), with periods of blank pages and redirects.

Originally a Chinese industrial company site (machinery), since 2025 it has undergone a drastic shift to gambling/casino (K8, 凯发国际) and further degradation to outright spam content (lures for free casino bonuses, "菠菜白菜论坛").

The domain started as the official site of a Chinese manufacturing company (嘉飞龙工贸有限公司) in 2006–2015, then from 2017 to 2025 it was in a state of constant redirects (302/301), and in 2026 it became a spam gambling/betting page (800全讯白菜网).

The main niche is industrial equipment (chains, conveyors), consistently present from 2017 to 2019. In 2020, the site fell under "Administrative Quarantine," after which the niche recovered, but in 2023-2025 the site was often under reconstruction or served empty pages.

Originally a site about the secondhand goods and equipment market in Zhengzhou (2018), then a long period of redirects, and in 2025 it turned into a spam online casino resource.

The domain had no content or was parked for a long period (2014–2019); since 2020 it has been consistently used for a fastener manufacturing company's website. There is no niche change, but content only appeared late in the domain's history.

Originally a Chinese company site for pipe manufacturing (2011–2018), then after a long period of inactivity and redirects, the domain was restored in 2025 with the same niche, but at the end of 2025 it sharply switched to explicit porn spam with keyword stuffing.

The domain was positioned for 6+ years as a corporate site for D-5AAA45 Corporation (B2B/industry), but in September 2025 there was a radical change to Chinese gambling content ("mg不朽情缘" — MG Immortal Romance slot machine). The link profile (260 referring domains) was built for a completely different topic.

Originally a site for an equipment manufacturing company (D-F34D30 LTD., 2008–2011). From 2013 to 2019 the domain contained no meaningful content (empty page titles), then transitioned through states like "home || D-F34D30.com", "New Document", "Index of /", and in 2025 switched to gambling/sports-betting spam ("世界杯官方网页版_世界杯（中国）」). The final state's niche is completely irrelevant to the original.

From 2019 to mid-2024, the domain was a blog/portfolio "visual stories – by isabel" (likely photography/design). After the drop in 2025, the niche changed to Chinese commercial sites (first livestock equipment, then "ATY平台"), completely unrelated to the original niche.

Originally in 2004 — Maltese company 'D-047FEE. Malta', but after a long gap from 2012 to 2022 it consistently operated as a Russian online store for LED lighting (EcoTrade). After the drop, starting in 2023, the domain was taken over and used for Chinese-language spam (casino, betting, pumps) with empty/spammy page titles.

Originally the site of a Chinese fan manufacturer (2013), then a sharp shift to a spam portal with movies/porn and links (2014), a long period of inactivity/parking (2015-2016), and a final transformation into a porn aggregator in 2021, later disguised as a "Blog."
