Fandom used to be a great Wiki platform when they were called Wikia, but now all they care about is its sweet advertising revenue. There are many instances on why this company only cares about money and ads:
1. They discourage wiki-farming (moving a wiki to another platform) and cite this reason for it. It's rare for a wiki to successfully farm over without Fandom's staff meddling around with it.
2. Their acquisitions from Red Ventures, including TV Guide and Gamespot/GameFAQ's all feel like they only bought them to increase advertising.
3. Fandom Wiki pages have way too many ads.
They also bombard you with useless information in regard to pop-culture news and BuzzFeed-like clickbait, which also are ads.
Everything on Fandom is nothing but ads here, ads there, ads all around and ads down there. Everything is an advert on Fandom (I mean, "Ad-dom").
