Plus has different behavior on Google mail, is why.

Foo+anything@ goes to foo@. This is an easy way to track who's selling your email.

Not every complaint you don't understand is invalid

Maybe that IS the reason some services treat it as an illegal character. They know how Gmail works and want to prevent you from figuring out what they do with your email.
