The “+” alias feature rarely works for me when registering for sights. They say invalid.

I have used “.” Variations to create multiple accounts on a service.

I wonder what the limit is?

Can I do …first.name@ and first……name@ and so on for infinite names!

iCloud has auto anonymous emailing with plus, Firefox does to, but tying my services to such a feature rather than even just an email seems fragile.
