F*NDOM (aka FanDumb) is a wiki host. It is usually used as the last choice if you are too poor to host it yourself. F*NDOM hosted Uncyclopedia and did so from 2008-2019.
F*NDOM is arguably the most widely hated website among the wiki community despite taking up 80% of the market, something about those annoying ads and slow as fuck servers. Also they never listen to you. Not to mention the terrible site layout.
