Yes, I understand that people do this. One consequence of doing it is that other people's replies are retroactively disconnected from the thing they appear to reply to.

I just don't like my replies being treated that way, is all.

Of course, I can't do anything to prevent it, and nobody else is obligated to respect my preferences. The best I can do is edit my replies to note that any disconnections might be retroactive, which is what I did.
