At one point in the future … bots will be buying cheap products and reviewing it with glowing reviews and recommendations to other bots who will also buy them and repeat.

Future space faring civilizations will wonder why this planet is filled with automated machines, digital systems that are all manufacturing, purchasing, commenting how great these products are no matter how useless they are, then disposing the products and endlessly repeating the cycle.

They will also wonder who the original inhabitants of this planet were and why they built such a strange system.
