Incelwiki.org was the first (known) explicit Incel Wiki, and was created and owned in very early 2018 by Nathan Larson, and before incels.info/incels.wiki/incelwiki.com. It was talked about on the forum Kiwi Farms even before incel.info/incels.wiki was installed.
It’s favicon was similar to the image that incels.info/incels.wiki later used as a logo, which seemed to have been by coincidence.
As of 2020, the website and domain are defunct, any subsequent versions probably won’t be the same wiki. No material from it was used anywhere.
