Words around text intrusions/image breaks and towards the start/end of lines

[dashstofsk]

 "d" is also usable in place of "s" for most of the words where it seems to be used as padding.

This is correct. Perhaps it helps to view the exchange for the most frequent words that start with these characters. It seems to suggest that these two characters are interchangeable when they appear at the start of a word. Almost always every  s word gives an  8 word. This is curious and in my opinion is evidence of artificiality in the text.
