Some services won&amp;#x27;t allow the + in gmail addresses, which is pretty annoying.&lt;p&gt;If a service starts recognising the dots don&amp;#x27;t matter and denying the plus symbol, there&amp;#x27;s a good chance I won&amp;#x27;t be able to register without obtaining a new email address.&lt;p&gt;I wouldn&amp;#x27;t mind but my name is really not that common -- my surname is uncommon enough for me not to have met another with that surname outside my family.</text><parent_chain><item><author>Pxtl</author><text>I have multiple &amp;quot;e-mail doppelgangers&amp;quot; - confused people who don&amp;#x27;t know their own email address and so accidentally use my address when they register stuff.&lt;p&gt;One&amp;#x27;s in Chile.
