Don't know if you're still looking, but anyways, here's a relatively big list of possible options https://www.mediawiki.org/wiki/Hosting_services and out of all of them https://miraheze.org/ seems to be the best fit (it's free, UK-based and should be ok for the most part; also I'm in no way associated with them I just want a nice wiki for the game)
Here are some links for your careful study with some thoughts after a quick read:
ToS - https://meta.miraheze.org/wiki/Terms_of_Use ; fairly standard stuff (nothing prohibited by UK law, no responsibility for incorrect info in user's content, some administration on their part, etc)
Privacy Policy - https://meta.miraheze.org/wiki/Privacy_Policy ; typical stuff for any hosting provider (stuff like sharing some rights to content to provide service), same as Fandom, non-registered content edits show IP address and registered show username
Content Policy - https://meta.miraheze.org/wiki/Content_Policy ; this should be most carefully scanned
Thank you. Yes, miraheze is a good option, and they specifically allowed such games to create wikis. The problem is they're absolutely free of profit, they pay for hosting because they're so generous. The wiki will get deleted if nobody will contribute to it and just occupies the space, and, judging by how it was going until now, contributors are not appearing. But it's an option.
That's a valid concern and I did miss the https://meta.miraheze.org/wiki/Dormancy_Policy but looking at it now there is whole section on exemptions from those rules, specifically for read-only oriented wikis, with a whole list https://meta.miraheze.org/wiki/Dormancy_Policy/Exemptions ; looking at them (there are some game wikis and even an eroge one), if asked nicely, ToA wiki definitely makes a valid case for an indefinite exemptio
