Ground control to Major Trial

I think the most depressing thing is how unsurprising this is.

This is why free trials require credit cards upfront, as they're more difficult to fake, not because you're about to be stealth billed. It's thanks to people like this.

it's practically trivial to bypass this if you really want to. CapitalOne in the US allows you to have virtual cards that can be verified but you can delete and block at any time for free if you have a credit card from them. I'm sure the practice discourages casuals from gaming trials, but it just feels like it's making life miserable for paying customers but doing almost nothing to stop bad actors

Those types of card numbers are detectable though.

How? Based on issuer identification number?
