There are some official wikis, the result of a licensing agreement. Those usually have a special tag.

In the case of small, one person-made games or webcomics, it's also possible the creator created the wiki as a knowledge base. But without examples, there's no telling. If you want to do it anonymously, contact staff via Special:Contact/general.
