I don&#x27;t know why you said that.  Gmail addresses can&#x27;t have +&#x27;s in them<p><a href="https:&#x2F;&#x2F;support.google.com&#x2F;mail&#x2F;answer&#x2F;12096?hl=en" rel="nofollow">https:&#x2F;&#x2F;support.google.com&#x2F;mail&#x2F;answer&#x2F;12096?hl=en</a><p>everything I wrote applies only and specifically to gmail.  it would be trivial to strip the +&#x27;s from every gmail address to get right into the person&#x27;s main inbox.<p>If I don&#x27;t trust a person to stop spamming me or sell my email address then I&#x27;m not going to trust a person not to do that.
