I notice two separate spambot answers to my question at Ways to make contact with aliens on a much larger size scale? that appear to be the same idea, with the same perpetrator though completely different text.
I've never seen this particular spam scam before. Out of curiosity, has someone with a good sandbox looked at the contents of the linked document? What's really in it?
More to the point, what is it about this question that attracts this bot? There are no illustrations in the Q or anywhere in the thread, at all! So, the first attempt at claiming copyrighted images is nonsense and I don't see why they would choose a post with no images for this. The second attempt is more vague about copyrighted material, and although I do quote from a story (my own), there's nothing about markup here that would indicate that something is an extended quote from another source so I doubt the scammer is looking for posts containing pasted materials.
