I took it as a poor-quality local model. I suppose it is possible, but it seems...unlikely... that one of the three responses to that post was a person who was so upset by the idea of serving junk content to scraper bots that they registered for an account, wrote their criticism, and then disappeared from the site.
At that time, there were a whole bunch of flagged-dead comments from newly-created accounts that had compound-word usernames (such as the text I linked to above from 'earlydeveloper'.) So, if these are people manually writing those posts, I understand the behavior even less than the bot hypothesis.
