Over 10 thousand worlds sterilized. Experiments, tests that have exceeded their utility. And then earth.
The human infestation had been notated and ignored. It is not unusual to find such a species.
Worlds with localized entities based on recombinatorial helical polymers usually tends towards mammalian phenotypes.
Large neural networks as found in the hominid cerebral cortex are well understood, and not unusual in this sector.
The appearance of the mammalian phenotype known as the 'panda', however, has not been predicted and requires further observation.
This 'web page' http://en.wikipedia.org/wiki/Panda_pornography intrigues us.
We have not yet taken over your planetary network as doing so is of little monetary profit to us and we are curious as to its evolution now that standard silicon based computational advancements seem to be steadying on your world, as to advancements in optical network technologies.
If you value the so called 'freedoms' provided by your primitive phenotype control structures then you will produce more of this so called 'panda porno' and will provide us with 7% of your Pandacoins (PND). Failure to comply with our demands is inadvisable.
You have two of your earth years. Thank you for your time.
