I recently posted a question in Mathematica SE, Can a package append its context to $DistributedContexts?. Out of idle curiosity I then googled for some of the code in the question, and I was very surprised to find a single hit at http://pastebin.com/cbM2wxjc, which looks like this:
These are all the code blocks in the question, and they appeared there within ten minutes of posting the question. Moreover, they are unattributed and contain no licence information. I reported the content as a Scraper using the usual procedure, but I have some questions.
How did the code end up there? This does not feel like your usual scraper, since they took only the code and not the context of the question, so it's hard to see how this paste would benefit anyone. Has this behaviour been observed before? Do we know who is doing it? Do we know why? I imagine it is not an automated SE mechanism, since the content is unattributed.
Should I do anything about it? Pastebin provides a DMCA mechanism which I'm tempted to use, partly because I have better standing than Stack Exchange as I hold the copyright, and partly to find out how DMCA takedowns look from the initiating end, in a setting with minimal damage.
