Maybe I overread it, but I didn't see it.

From paragraph 7: "He has been accused of taking credit for other people’s research and even using multiple aliases on Wikipedia to make it look as if people are agreeing with his posts."

"Has been accused". Evidence lacking.

I do not take a position on the accusation. The purpose of the comment to which you are responding is to support emmelaich's assertion that the accusation is mentioned in the article.
