Expired domains in education and courses

Initially the niche was related to firearms training and concealed carry (2022). The final niche before the drop was Asian gambling spam (2025).

Stable niche of personal growth and online education (Escola de Crescimento Pessoal) since 2023. No niche change recorded.

The domain has changed niches multiple times: it started as a regional news portal (曹妃甸信息港), then switched to IT training, back to news, and after a long chain of redirects — to gambling (乐鱼体育, 九游会) and VPN (梯子加速器, 佛跳墙VPN). The final niche before the last snapshot was VPN/加速器.

Originally — the official website of Dinas Pendidikan Provinsi Kepulauan Bangka Belitung (education). Within a short period (less than a month), the niche switched to gambling (Togel Hongkong, HK Lotto).

Initially the site was a digital marketing agency, then it switched to online courses, after which the content disappeared (empty page titles) and the domain degraded to a technical placeholder ("Index of /") and chaotic redirects.

The domain was a stable personal blog about technology and education in South Africa from 2009 to 2020. After the drop, the niche shifted to a doorway page (United States guide), then to a technical placeholder (Apache), and in 2025 — to gambling (Toto Slot Gacor Thailand).

Originally (2008–2011) — the website of the Turkish driving school Esenler Tepe Sürücü Kursu, focused on driving instruction, exam questions, and license categories. Later (2014–2017) the content degraded to "Untitled Page", then (2024) the domain was taken over by escort ads, and by 2025 it became a Chinese gambling portal (爱游戏平台). In total, at least three complete niche changes, with the final one unrelated to the original driving school and its accumulated link profile.

The domain started as an educational resource (D-62400B for art education, 2016), then switched to the PresentAsian App (2018-2022), and finally degraded into gambling in Chinese (lotteries/飞艇, 2024-2026). Three drastic niche changes in 10 years.

The site originally sold Los Angeles Chargers jerseys (2019-2020), then was repurposed into a Persian-language education site (2021-2023), with the final niche before the drop being gambling (S8TOTO, slots, toto). There was a triple niche change.

Initially, based on the domain name and a single appearance in 2025 ("Home - D-65309A"), the niche was related to preschool education. However, a shift to gambling/betting (KUBET, Togel, Slot Casino) was recorded, with the final and most frequent niche before the last drop (2025-08) being bookmaker/casino, which is completely irrelevant to the preschool niche.

Initially (2005–2015) the site consistently represented a Chinese IT school (北大青鸟 / 状元廊), then (2016–2022) — children's robotics («凤凰机器人»), the final niche before the last snapshots — adult/spam («香蕉视频app»). The niche changed at least three times, the last one being outright questionable.

The domain was originally used for a school website (Shloka a Birla School), but before the drop it was taken over and turned into a spam landing page for an online casino (AIRBET88).

Originally the site of Dinas Pendidikan Lahat (education office, Indonesia), in February 2026 it abruptly switched to spam content in the gambling niche (Hong Kong lottery).

Originally (2008–2017) the domain was used as an educational blog about Washington (The DC Education Blog). After the drop, the niche changed to a Chinese online casino (2019), then to VPN/proxy services (2025–2026). The final niche (VPN) is completely irrelevant to the original one, for which the link profile was built.

The domain was originally used as an educational portal/LMS with a login page ("D-710AE1 - Login") from 2011 to 2016. After a long period of inactivity and a blank page, since February 2025 the domain has been taken over by Indonesian spam gambling (Togel).

Originally (2016–2023) a student hackathon site, stable event niche in tech and startups. From 2024, a sharp shift to Indonesian gambling doorways: first Raja99, then PAHAM4D and other slot brands; current niche completely mismatches the original.

Multiple niche changes: Chinese fashion (2005-2006) -> Japanese tutor reviews (2009-2010) -> Japanese plastic surgery (2011) -> Chinese adult content (2020-2021) -> Chinese casino/scam "华纳公司" (2022-2025). Final niche — fraudulent site with a phone number.

Originally the site was dedicated to the poetry of Charles Baudelaire and the collection 'D-5DF3AC' (literature/education niche). In 2016-2017 there was instability with empty page titles, and in 2025-2026 it fully switched to spam content for online casinos and slots (CUPUTOTO).

Originally (2017-2020) a Japanese site under the generic name "D-8EAD5C". In late 2023, it abruptly shifted to a French funnel site teaching how to earn from Google Discover, which lasted only a few months.

Originally the site of a German boarding school (Internat Schloss Loburg) from 2018 to 2021. After the drop, the domain was re-registered and now hosts Chinese content (振磊阅读楼) — a complete niche change.
