Actually, they've already got one, and here's how it works:
1. Put up a free porn site.
2. Present somebody else's capcha image as an entry.
3. Let the person see the porn if they've correctly cracked the
capcha.
4. Spam site.
The sad part of this one is that they don't have to crack any single
capcha system. Instead, they've cracked the entire capcha process.
Cheers,
