Does it really apply if you don't do the bare minimum? I wouldn't complain if they were fighting automated building of sophisticated account networks that guide you towards some hidden ad. But until they do a pattern match on the most popular spam words used every day, Red Queen is not an issue.

yeah that is the purpose of "show more". It is designed to hide spam
