The bigger smell is no version control :D Saving emails `onBlur()` is probably not a dark pattern.

You're getting downvoted while being right. A dark pattern is tricking the user. Not saving the data they enter. But most people around here call anything that is distasteful a dark pattern.

It is a dark pattern - it tricks the user into thinking their data won't be submitted until they click "submit," but instead saves it right away. It would only not be a dark pattern if the form clearly said "your email address will be uploaded to our servers immediately after typing it."
