Hi, those pages aren't plagiarized. What happened was around 8 years ago, TFWiki was located here, however the community and Wikia stuff had a difference of opinion - you can read some of the complaints here,

Because the text of the wiki is under a free license, the community was able to transfer it to alternate hosting as TFWiki, however because Wikia is not a simple website host, they were also able to keep the copy of the wiki here open and able to be edited.

That is why many pages which have not changed much since 2008 have the same text both here and on TFWiki.

So long story short, I can see why you'd think that someone had plagiarized those pages, but it's only plagiarism if someone copies stuff added to TFWiki after 2008 (and obviously if someone copies stuff from Wikia to TFWiki) though there are exceptions.
