A comment on Email address validity checks suck.

I don't get why they do this.

Email validation can be done by sending an email to the specified address. Why bother differentiating between "invalid" and "valid but doesn't exist"?

Just check there's an @ symbol with something before it and something after it and if so, send it an email.

Any reason not to do it this way?

They don't want you to use disposable emails, so they make whatever check they find reasonable to prevent it.

I hate it, of course, but that's what they do.
