The problem with the TARDIS Wiki is their neutral point of view rule which treats all media and writing equal. Fact of the matter is, it isn't equal. It makes sense for most franchises, but not Doctor Who, even with lore inconsistencies aside.
They can commit to the idea there is no canon as much as they want, but it doesn't make it any less true. Most fans would agree with this.
Ideally the wiki should have something similar to their valid/invalid source system, but tiered. There really isn't any better way to document a franchise that was never designed for such an in-universe wiki and loose copyright. Needless to say, when the wiki gets to the point when they're having to canonise Family Guy and Star Wars fanfiction, and also stories where the writers have deliberately written them knowing they'll get on the wiki, then they really need to look long and hard at their rules of what they cover.
I've seen that Peter Griffin Gevity comic get mocked not just here but on many other fandom spaces. How these wiki editors don't see that article as an embarrassment is beyond me. Surely not all wiki editors are happy about this?
