That's not the actual mechanism, as far as I understand. If the content-type is text/plain, the server will pass it through just fine. It's the mail program at the sender end that refuses to send .csv files and friends as text/plain, based on the extension. But the net result is essentially the same.

Would be good if someone could ask the authors about what is going on. Better if someone could check licencing issues and put the data somewhere permanent. Still better: convert them to an R package.
