Copying data is wasteful, mutating data is dangerous

Why does this blog post have a recaptcha?

In addition, I just finished reading the Rust book last night, and I don't believe this is what interior mutability is (at least as used in Rust).

I'm using ConvertKit for newsletter signups, and choices are either:

1. Validate emails with recaptcha (which is why you see that thing in the corner.) 2. no email validation at all, so random people get spammed with confirma-you-want-to-subscribe emails.

I am not super-happy with having to make this choice :(

For the email box, presumably he doesn’t want bots entering emails.
