Expired .cc domains with a past

Originally a one-day lottery prediction page (2018), then operated for several years as a lottery/betting forum (2019–2022), after which it switched to a pornographic doorway (from 2025). The final niche (adult) is completely irrelevant to the period of backlink growth.

From 2011 to 2022, the domain was an English-language hub for architecture and research (successively "D-EF9F1D - hub for architecture and research" and "Main : D-EF9F1D"). After the drop in 2022, the niche chaotically shifted to Japanese content about infidelity, then to spam pages with pornographic keywords.

From 2015 to 2018, the site was a Russian-language resource titled "Shadow Economy"; in 2020–2021, it turned into a forum for shadow services and a deal guarantor on the Darknet, then went into redirects, and in 2025 it serves Chinese porn content with keyword over-optimization. The niche changed multiple times, and the final version does not match the link-building period at all.

Initial niche undetermined (page title “D-07C5FC,” possibly a fan project or a placeholder). After a long gap and a series of redirects(2014–2015) the site turned into a spam page with a scam page title “D-07C5FC.org Prize Africa”. Thereafter the niche changed repeatedly and chaotically: from project plan templates and children’s coloring pages(2019–2020)to a Japanese site comparing English lesson prices(2022)and, finally, Chinese porn spam(2025). No stable niche ever existed; any accumulated link profile is, in all likelihood, not relevant to any of these short-lived directions.

Multiple niche changes: from KTV nightclubs to fountains, then a people-search platform, and finally outright spammy adult content (Asian AV) before the drop.

The domain originally served as a placeholder page ("Welcome to D-DD671D.cc") with no real content, then abruptly turned into a spam doorway page with aggressive keyword-stuffed page titles targeting the adult niche (Japanese-Korean porn). Complete lack of thematic stability and relevance.
