block user for sometime after insert a data from his ip
<p>I want to block a user for 5-10 minutes after he add some data to server....
It is just like for security...A user can not insert data more than 1 time for 5 to 10 minutes.
Or if I insert something then the javascript function which calls the inserting code will blocked for 5-10 minutes...</p>

<p>Thank in advance..</p>
