In the last few weeks, I frequently see some empty comments. It’s just the username and no text beneath.

Is there a deeper reason behind this? Do people nowadays strip away the text instead of deleting a comment? Or did some script surface that ‘makes the internet forget’? First I thought people did this before deleting a comment and the deletion just didn’t get federated. But I scrolled through some older posts and they also still have comments like that, so that can’t be it. Right?

Can anyone educate me?
