title: Regex that does excludes characters that repeat (3) three or more times
body: <p>I'm looking for a regex that searches a file and does NOT return (i.e. it excludes) chars that repeat 3 or more times consecutively in a string. I've tried this expression below, but it's NOT doing the the job :( ..something that looks fwd and backward and excludes strings that have 3 or more repeating back-to back chars. i.e. it should return <code>abcdefg</code>, but not <code>3333ahg</code> or <code>gagjjjjagy</code> or <code>hdajgjga111</code></p>
  
  <pre><code>(?!(.)\1{3})
  </code></pre>
