I've got a lot of users who apparently can't read. Despite numerous notices to only press the submit button once, I have users who:

A) Can't Read
Are Impatient
C) Think pressing the button more will make it go faster
D) Need a swift kick in the arse
E) All of the above

As such, I have a ton of duplicate records in the DB which I need to painstakingly remove.

Is there some sort of script to protect my users from themselves?

I have exactly the same problem and I would like to get a solution. Any idea?
