I really want to like the gmail trick with . and + but I've run into issues many times with websites that don't share validation code between registering for a service and logging in. I've had situations where I've been able to register for something fine, but the login form breaks saying + is not valid. This often leads to having to call customer services and explain to a confused rep the situation. Additionally as others have mentioned I'd imagine a lot of websites who do permit these addresses are already "normalizing" the address anyway and storing that instead

> I really want to like the gmail trick with . and + This is not a gmail trick. It has been in common usage at least since the very early 90s (but may predate that), it was a fairly universal convention.

  It's not universal, though. When my local university switched over from Gmail to Office 365, they made the ingenious decision to disable + aliases at the same time. Emails to unknown addresses are rejected like any non-existent email address. This means that anyone who registered an account with a + address could no longer access their services. Hope nobody forgets their password for that one critical service that doesn't let you change your email address!
