Are you still not convinced that you shouldn't buy games that use Starforce? From Gadget Life:

Now, Futuremark has uncovered a very dangerous anti-piracy system Starforce is now using. This copy protection system installs a driver that runs at the highest level of access on the system, which gives it low level access to the PCs hardware and any drivers and processes. This driver runs regardless of whether the game runs; keeping an eye out for any suspicious activity such as attempting to copy a protected disc. If something suspicious is detected, it forces the PC to make an immediate reboot, regardless of any other applications running and whether or not the user has any unsaved work.

Gee, why would anyone not want to purchase a product that relied upon Starforce for its DRM? According to a Starforce PR spokesman, it is because they just must be members of the Russian mafia:

StarForce Technologies, for its part, often takes extreme offense to negative comments... ...When questioned, Zhidkov [SF's PR manager] told us, "The issue on StarForce is obviously sponsored by our competitors or organized crime groups that run CD/DVD piracy [operations]. We are now in close coopreration with [US and Russian officials] investigating the matter and trying to find out who stands behind the boycott campaign.

That quote was obtained from the latest issue of Computer Gaming World.
