Has anyone tried to check out the FANDOM wiki alternatives, like miraheze?
I've looked at a multitude wikis hosted on alternative service platforms. Funnily enough, most are FANDOM/Wikia refugees that either left to get away from FANDOM's bullshit, or were forced out by FANDOM because of their clamping down on content.
An example of the former are the
NIWA wikis. NIWA stands for the Nintendo Independent Wiki Alliance, and its a group of independent wikis focused on, as the name implies, Nintendo products. There are
32 member wikis, many of which weren't members when they started, so they've grow quite a bit. This includes the infamous
Bulbapedia, whose main site,
Bulbagarden, was the subject of a Metokur video. Ultimately, I use these wikis over the wikia ones, as they are a good source of information. Note, not all members wikis are Nintendo focused (for example, the Dragon Quest wiki is a member). Another example is NIWA's main affiliate,
SEIWA, or the Square Enix Independent Wiki Alliance, which is like NIWA for Square Enix (the Dragon Quest Wiki is also a member of this group). These wikis, being independent, are not hosted by Miraheze.
An example of a wiki forced to go independent due to censorship is the
Monster Girl Encyclopedia wiki (NSFW). It uses Media Wiki, just like the Nintendo and Square Enix wikis, but unlike those, this one is hosted by Miraheze. MGE Wiki was a FANDOM wiki until a few months ago, and existed there peacefully for years, keeping its status through careful censorship of images. Then suddenly, round about October and November of last year, FANDOM decides the wiki is too risque for them all of a sudden, and gives the wiki a few weeks warning before they close it, later giving them one or two extensions. That began one of the fastest wiki migrations I've ever seen as wiki administrators rushed to transfer everything over to their new Miraheze wiki site before FANDOM closed them down. It seems to me that they were largely successful in saving all of the content pages, though forums, fanworks and such are probably gone.
For an example of an independent Miraheze wiki that isn't a refugee from FANDOM, there's the TvTropes fork,
All The Tropes, whose administrator is actually a member of our little site.
If you want an exhaustive list of independent, non-Fandom wikis, try
WikiIndex, which list every wiki ever. It also provides a handy list to
Forked Wikia wikis, which left Wikia/FANDOM, and
a list for those that were forced out due to censorship.
