Very interesting question. I think that's a nuanced distinction that very much comes down to exactly how the other person suggests getting off facebook. If I get the impression that the commenter cares about the well-being of somebody and suggests it as a solution, I tent to categorize it as "good advice". Example: "I had the same problem / know of people who had the same problem, getting off facebook seems to help". On the other hand, when it's a barely related topic (nothing about mental health, only related to the company) + there's no actual person to care about + the comment is very standoff-ish, I jump to virtue signaling. Unsolicited advice, especially when given in a tone like this, is often much more about the giver of the advice than anyone else imo.
