Expired .org domains in education and courses

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 domain lived for 15 years (2001–2016) as a legitimate Japanese NPO center (D-66EC79 Center), then abruptly switched to English-language woodworking content (2016–2017), then to food in Kanagawa (2019–2022), followed by chaotic shifts to children's ballet, preschool education, and finally Chinese spam content "黑料不打烊" (2024–2025). The link profile was built around Japanese NPO topics, but the final content is clearly spam.

Initially the site was dedicated to STEM education (2021–2023), then, after a period of instability and empty page titles, the final niche before the drop shifted to a Ukrainian online casino (2025). This is a radical niche change, and the link profile built around education is completely irrelevant to the gambling niche.

Initially (2010–2014) a stable site for the Home Builders Association Manatee-Sarasota, then in 2017 the content switched to Japanese spam about correspondence high schools (通信制高校), after which the domain alternated between redirects and an empty state.

From 2006 to mid-2025, the site was dedicated to Tai Chi Chuan and Qigong in Germany (training, certification, DVD). No niche changes occurred.

Initially — an academic site for a research center at Renmin University of China (2010–2013). Then domain parking (2014–2016), a French streaming site (2017), a Chinese site '忍蛙网' (2017–2022), and finally an Australian lottery/gambling resource (2023–2025). Final niche — gambling.

Originally (2004-2007) the site was dedicated to training on protected natural areas ("Protected Areas Learning Network"), then after a long period of inactivity (empty page titles) it went to domain parking, and since 2017 it was hijacked and used as a Japanese doorway/spam site in the adult niche ("風俗ヴァージン" — Virgin Customs/Fuzoku — a term related to the sex industry). The final niche is completely irrelevant to the original one, for which the link profile was built.

Originally (2012–2014) — a Chinese NLP project D-85FD52 (Chinese text segmentation, machine learning, AI). After 2014–2016 content disappeared, the site showed empty pages/nginx, from 2023 to 2025 — 302 redirects to an unknown domain; no final niche before the drop, effectively none.

Originally an elementary school site (D-2FA123 Elementary School, Baltimore) from 2023–2025, switched to gambling (Warga88 — online casino) in September 2025. The niche change is radical and occurred right before the drop.
