If you let your hacker hit that many major systems with no ill consequences, it's not the game that made it that easy, it's you. It's your job to instill a sense of reality and consequence. It's your job to make the government and corporations something to fear, not just mindless and weak corporations.
Damnit man.

um he only had to hack 2 systems, the local court system(not exactly a AAA) showing the decison went to lone star x and a local doc wagon facility,(agai not exactly a AAA) forging a doc does not require them to hack a system all they had to do was put it in 2 places. The adventure gave them a long time and the long hack is stupid hard to stop in 4e.
1. I don't artificially increase the challenge to make the run more dangerous/difficult
2. I actually use the matirx rules.
3. I don't bone people because they came up with a good plan and I want things to be hard for them.
You are right though, I had one job. To run a fun adventure, I succeeded.
