I believe they no longer allow new accounts without an email address.

It used to be that reddit had a user creation screen that looked like you needed to input an email address, but you could actually just click "Next" to skip it.

The last time I had cause to make a reddit account, they no longer allowed this.

You're right, it looks like these days you have to fill in an email address. Though any random thing can be filled in. They will send a verification code, and on the next screen you can either fill it in or click Skip in top right. Then in the preferences, it can be removed from the account. A bit annoying for sure, but still not valid email address needed.

But it is true that at any time they could make using an email address or phone number mandatory, and then creating an Advent of Code account will be gated behind that.

You can use a garbage email address, you don't have to verify it
