I used to run it, but now I intentionally do not. For what it's worth, I think it's a neat way to catch an extraterrestrial computer virus. Even if aliens know nothing about our computers, they can make some assumptions and given the timeframe and the sheer processing power that the distributed computing provides, they can make it work. It least, it's easier to make some assumptions about an unknown computer than some assumptions about an unknown form of life. What do you think of that?
