If a streaming company is greedy and lets you use the same card each sign up, you can indefinitely use their service for free using an endless supply of free emails.

I had Foxtel Go, an online pay tv service in Australia, for free for 2 years before I got bored of it, I think I fucked up like 3 times and had to pay, but as long as you cancel it a day or 2 before, you’ll be fine.
