title: Find all numbers that are present more then 3 times in a column of CSVs
body: <p>I basically want this: <code>if certain number is present &gt;= 3 times then do some action ...</code></p>
  
  <p>My table's column is this: <a href="https://i.stack.imgur.com/f3oeC.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/f3oeC.jpg" alt="enter image description here"></a></p>
  
  <p>As you can see here that number <code>38</code> is present >= 3 times in <code>absent_sids</code> column, so I want to have some actions on him like ban or something else. But I don't know what sql query should I write because;
  1. I am quite new to php/mysql
  2. The column has comma separated numbers, and its quite difficult for me to search in this column through mysql query and bring the <code>absent_sid</code> that is >= 3 times in a given period of time/date.</p>
  
  <p>Plz help</p>
