Being in the graphic design business, it’s frustrating what a customer doesn’t send their branding-designated fonts. Adobe has a lot available, but not everything.
I’ve found that the best resource for finding expensive or niche fonts is VK.com. There’s a big font sharing community there, and you can usually find what you’re looking for.
You don’t need to sign up, you can search the whole site by googling site vk.com "font" "your font name here"
Do you really want to be caught pirating fonts on commercial, very much publicised, work?
It’s one thing downloading shit for home usage. The moment you go commercial, you can be fucked six ways to Sunday in so many countries.
That, and you’re publicising your own evidence to be used against you. If the rights holder doesn’t have you on the books, they can get organisations like FAST on your ass quickly.
