That is unless the spammer was clever to do the following:

  providersWithSuffixSupport = ["icloud.com", "gmail.com", "googlemail.com", ...];
  if email.endsWithAnyOf(providersWithSuffixSupport) {
    email = email.trimBetweenFirstOccurrence("+", "@");
  }

I have a site with users, and while we have no interest in selling their addresses, it still strikes me as futile when people add "+mysite" to their address. It would take me 2 seconds in excel to zap all those appendages.

Not everybody uses the scheme for some futile security purpose, some sites are just a bit annoying with their outgoing addresses with their non-nefarious communication and the + scheme can be a nice way for rules.

I hadn't thought of that case. I've always had good luck simple simple rules like, "if @theirsite.com then move to folder".
