Exactly! But its not obvios. So most of those shitty websites don’t even know they have a problem.
Then there are also people ignoring it on purpose. I once read a reddit comment saying 'well of your address looks like “John wick 🐶❤️”@2001:0db8:85a3:0000:0000:8a2e:0370:7334 I don’t event want your email in my DB because oit will break something
I have a feeling, the ones codapine is stating, didn’t even care to half-read the spec and just went with what they knew from experience.
Maybe they didn’t even know there was a spec.
Maybe they asked ChatGPT for the regex.
I’m not sure I blame the sites. The spec is so complex that it’s not even possible to know which regex to use
Yes. Almost like a regex is not the correct tool to use, and instead they should use a well-tested library function to validate email addresses.

const emailRegExp = /^[\w.!#$%&'*+/=?^`{|}~-]+@[a-z\d-]+(?:\.[a-z\d-]+)*$/i;per the HTML specification. From https://developer.mozilla.org/en-US/docs/Learn_web_development/Extensions/Forms/Form_validation#validating_forms_without_a_built-in_api
That’s one very random place to find that. There are a lot of different one and there is no way we all just agree to use that one.
Look art his site that shows a more complete and (in theory) official website. While also explaining that there is no regex that is perfect

No. But it’s on the form validation topic.
