For me the whole post appears as written by Daneland (as shown as screenshot by Danelend in the post after it).

If you see that differently on your end, it would be good to check that out, because it is a massive problem if you can't be sure who posted what... it's not about quoting at all. It's David accidentally posting as Daneland (likely only possible because of Team member status, I assume?).
Here once more a screenshot of what I (and likely others) see:
