Not OP, but the title seems to imply the author hacked LinkedIn and got 120k out of it. Whereas the author simply figured out how specific he could use LinkedIn's ad targeting to impress someone who was giving out 120k.
Title is definitely a bit misleading, but at the end of the day, you gotta do what you gotta do to get the clicks.
Correct, but even YC classifies that as a hack. If you have ever checked out the YC Application they ask of a time where you have hacked an existing system to make it work in your favor. If this doesn't qualify as a hack then I don't know what does.
