Lol yes. It's intentional. It stops spam bots from trying to sign up, since we aren't open for signups yet.
But don't worry, you're not the first to mention it. I suppose I should just fix it and deal with the spam like normal.
I liked the unintended effect of cutting down on spam. I guess a lot of spam bots are written on top of standard libraries that reject bad certs. :)
Also, this was ironically a great way to publicly call someone out for a seemingly bad decision without being cruel about it, so props to you!
