@Adam_Cadmon1 no but it is a common one. However there are many other modes that I see (especially here but also across other social media going back 30+ years)

- acknowledgement of someone’s pain or joy (more common in semi-private groups or media than public - ie an alumni group or a FB post from a friend. But I’ve seen this in shared interest communities also
