Back when I actually used my Gmail account, I found LOTS of sites that would refuse to accept an email address with a + in it. I attributed this to a mixture of incompetence and active malice.

These days I host my own mail server and use . as the sseparator, which has been working well for years.

I stopped doing this after I encountered a website that accepted + in the registration form but not the email confirmation.

more likely the js snippet or regex they C&P from the interwebs disallowed it.
