Expired .com domains in education and courses

From 2019 to 2024, the domain was consistently used for a conference on the internationalization of higher education. In 2025, the topic radically shifted to spam content for casinos/slots with the title "RIBUT4D: Situs Slot Online Terpercaya, Gacor & Resmi 2025", which is completely irrelevant to the original link profile.

The domain consistently served music services (lessons, instrument repair, audio production) from 2010 through early 2023, then pivoted to event planning in 2023–2024, and was repurposed for a blog about lottery strategies by 2025 — a clear deviation from its original niche.

From 2013 to 2022, the domain was consistently used as the site for NPO法人鹿児島ASC (ICT training for seniors, niche — education/social services). Since 2023, the niche has changed multiple times: YouTube trends (チュートレ), idol profiles (アイトレ), fortune telling (天使のスピリチュアル占い), and finally — Vavada casino (2025). That's 4 niche changes after the drop, the final one being gambling.

The only content period – the site of the Vietnamese secondary school Hàm Nghi (late 2016 – early 2018); before and after – years of 302 redirects of unknown purpose with no recorded niche.

Until 2017 — a stable Chinese site for business coach D-EF7862 (corporate training, leadership). Since 2018 — domain hijacked by spammers: first a casino doorway (bet365), then porn spam. The niche has radically changed, and the link profile built on coaching content is now irrelevant.

The site started as a paragliding school in Portuguese (2013–2019), then was parked (2021–2022), and in 2024–2025 turned into a Chinese gambling doorway. The theme changed drastically, and the final one has nothing in common with the original.

Originally used for the brand "D-9E75E9" with the niche "Art, education, empowerment" (2021–2022). After 2022, content stopped being captured: a series of 301/308/302 redirects, domain parking, and empty page titles followed. The final niche before the drop is not expressed, which makes it impossible to determine the relevance of the link profile.

The only niche throughout the entire period — the site of the Indonesian public school SMP Negeri 35 Kota Bekasi (educational, local). No niche change; after 2020, content disappeared, and the domain transitioned to an empty directory/parking state.

Originally, the domain was the official site of the education office (Dinas Pendidikan Aceh Selatan) with an educational focus. In the latest snapshot (2026-02), it drastically shifted to a spam site dedicated to lotteries (Togel Sydney) with aggressive keyword stuffing in the page title.

Originally the official website of the Siak Regency Education Office (Indonesia); the latest snapshot shows a sharp shift to gambling spam (Togel Sidney).

Throughout its entire historical period (2003–2018), the domain hosted a German-language site about studying in the US. After the drop, the niche shifted to casino/gambling (2024–2025).

Initial topic (2024-05) — a Chinese educational company '项城兆邦教育有限公司'. Then in 2024-2025 the domain went through a series of 301 redirects, and the final content (2026-04) — '乐玩手机版-乐玩lewan(中国)', which is typical of online casinos/gambling. The topic changed at least once: education → gambling.

From 2012 to 2017, the site was a consistent blog about SEO/SEM training and making money online. In 2019, the niche completely shifted to a mobile gaming portal, and since 2024, redirects and domain parking have been observed.

Originally (2013–2018) the site was a stable educational project "D-6A578C" (training, courses). After a period of instability and redirects, the domain was taken over and turned into a spam resource linked to online casinos and toto (KAWANLAMA88, RATUKIDUL88).

Originally a blog about Tokyo ("D-F1AB05"), then a Japanese diary ("佐知子の日記"), then gambling/casino ("東京カジノスタイル", "Gamingbet99"), with bits of betting affiliate content ("D-F1AB05.com m88") and random Japanese content about schools.

The domain started as a legitimate TEDx event site (2010-2019), but from 2020 there was a radical shift to Chinese gambling content ("大发快三规律" — lottery/gambling), then to Apache parking. The final niche is completely incompatible with the original link profile.

Originally a children's art education site (2015), then pivoted to gambling and lotteries (2017–2018), followed by blank pages and redirects, and since 2025 it has been used as a catalog of free comics. The niche changed at least three times, and the final one does not match the niche that built the bulk of the backlinks.

Initially parked, then a long period (2014–2020) of religious content ("Why believe in religion?"), then parked again, in 2023 — machine learning, finally (2025) — a Chinese online casino (华体会). The niche shifted radically, the final one is spammy.

From 2013 to 2020 the domain hosted a business leadership blog (“D-7926B1”) with articles on management and entrepreneurship. In 2021 it was dropped and picked up by a spam network; the Wayback Machine shows only parked pages after 202agogo.

Originally (2017–2018) — a store for counterfeit NBA jerseys (Cheap NBA Jerseys From China), then a long parking period, from 2023 — porn content in Chinese, from 2024 — an Indonesian gambling slot (KAYARAYA). The final niche before the drop was casino, unrelated to the original one, which is likely where the main link profile comes from.
