There's a demand, why not supply it, and make money while you are at it?

This reminds me of the RMT driven botting problem in WoW (World of Warcraft). Instead of fighting the neverending game of cat and mouse against botters, Blizzard just decided to supply the long reprimanded demand for in-game currency by creating the WoW token, and they make money while they're at.

If such a simple mitigation as adding captchas worked then it seems like the value is pretty marginal, plus it sounds like the limit is upstream.
