Logistical is not a spam game. From the news story on spam games:
What are achievement spam games?
The definition is a little subjective and should be based on a per-game basis, but to put it more broadly, these games will throw hundreds, sometimes thousands of achievements at you with little-to-no effort required.
While Logistical has thousands of achievements, the game does not throw them at you. As evidenced by its numbers...while over 200 users have the game, only 4 have completed it.
I hope this answers your question.
