title: Spotting similarities and patterns within a string - Python
body: <p>this is the use case I'm trying to figure this out for.</p>
  <p>I have a list of spam subscriptions to a service and they are killing conversion rate and other usability studies.</p>
  <p>The emails inserted look like the following:</p>
  <blockquote>
  <p>rogerep_dyeepvu@hotmail.com</p>
  <p>rogeram_ingramameb@hotmail.com</p>
  <p>rogerew_jonesewct@hotmail.com</p>
  <p>roger[...]_surname[...]@hotmail.com</p>
  </blockquote>

  <p>What would be your suggestions on spotting these entries by using an automated script? It feels a little more complicated than it actually looks.</p>
  <p>Help would be very much appreciated!</p>
