I think maybe you don't know what 'weasel words' mean.

From Wikipedia:

In rhetoric, a weasel word, or anonymous authority, is a word or phrase aimed at creating an impression that something specific and meaningful has been said, when in fact only a vague, ambiguous, or irrelevant claim has been communicated. The terms may be considered informal. Examples include the phrases "some people say", "it is thought", and "researchers believe". Using weasel words may allow one to later deny (a.k.a., "weasel out of") any specific meaning if the statement is challenged, because the statement was never specific in the first place.

There's none of that here.

Summary review:

The passage does not contain significant weasel words. It acknowledges uncertainty explicitly with phrases like "I may be wrong," "I would guess," and "I assume," which actually counteract weasel wording by qualifying claims. The author distinguishes between fact and opinion, admits lack of knowledge about the individual, and provides a source for a factual claim about social media as a news source. Overall, the language is transparent about uncertainty rather than using vague or evasive phrasing to appear more confident than warranted.
