There's a reason Wikipedia isn't an acceptable source in college-level courses.
If the reddit admin edits of comments aren't appropriately stored in comment history, the logs turned over won't tell the whole story, but reddit will (mistakenly) testify that it's the complete history.
You can even add a dash of malice: an exec edits a rival's post, but the subpoena is filled by a line tech (possibly unaware of the admin tools, even).
Unless the defense knows to press reddit on the actual veracity of their logs and ways they could be compromised, the erroneous data seems a fact to the court.
