By the very definition of Spam, this singular post does not qualify, unless you want to rewrite the English dictionary: spam; verb
gerund or present participle: spamming
send the same message indiscriminately to (a large number of Internet users). The sending of multiple unsolicited e-mails or text messages, usually for marketing.

This post was clearly NOT spam, whether you think it is or not.
The Cheetah bot at least provides an upvote and links similar posts, rather than set out to destroy reputations on a singular opinion, something to consider for the happy community here on Steemit.
