Disagree.    The old format was way too easy for groups to manipulate, report comments, have users blocked (which happened after a certain number of "report comments" was made.)     This system, while far from perfect, is more open.    You can even see names behind the reactions - giving more meaning vs the useless thumbs up system of the old format.      It's also far easier to follow threads as well as responses using your profile.    Seems to work better on an iPad and phone than the last system too, at least for me.

Improvements would be to grey out "uncivil" posts vs deleting (and keep them in your profile), and keep a longer history of posts in your profile.
