Re: Plus sign in email addresses is often fun
I had an account on photo.net which (a) changed at some point so it would not let me use my account-with-+-in-it and (b) kept on sending me junk mail to that address and ignored my requests to delete it or make it work again. If I had more than one suitcase nuke I think I would have used one of them to deal with this cretinism.
There are, I believe, RFC-822 parsers out there (as in: there are hundreds): why can't these fuckwits just use one to tell if email addresses are valid rather than use some half-baked regexp of their own devising which doesn't actually work.
