F*NDOM is a wiki host. It is usually used as a last resort if you are too poor or unskilled to host it yourself. F*NDOM hosted Uncyclopedia and did so from 2008-2019.
F*NDOM is arguably the most widely hated website amongst 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 your bickering. Not to mention the godawful site layout.
