I use a few dozen novels in a single text file and randomize which lines the script pulls. It then replaces the text three times with a random pull. What you end up with are four responses in plain English. Which is the real one? You could filter out responses edited after "the great exodus", but I have been doing this to my comments a few times per year during my twelve years on reddit.
The truth is that even if I don't get them all, I get enough that it makes it far easier for the group that bought the data to just filter my username out rather than figure out what's junk and what isn't.
