For (strKey in FORM){
FORM[ strKey ] = REReplaceNoCase(
FORM[ strKey ],
"([\w]{1})(\1{2,})",
"\1",
"ALL"
);
}
This gets the first group (which is any letter or digit) and checks to
see if that is followed by 2 or more instances of that letter. If so,
then it is replaced with a single version of that letter.

Subject: Preventing long strings of one character
I'm building an email signup form for kids. Sometimes they (or their
adults) type in values with long strings of one letter:
ddddddddddddavid for example.
I'd like to loop over the form fields and check for any occurrence of
one character repeated more than 3 times. That should cover any legit
instance.
I'm guessing that this would be a cause for REReplaceNoCase, but I'm not
certain what the regex would be. Anyone have input? For simplicity's
sake, I'll just search for any letters or numbers.
So I want to find any occurrence of 4 or more letters or numbers in a
row. I was thinking that this should work, but it's matching whether
there's 3 or more letters in a row or not:
<cfset mystring = "waaaaaalt">
<cfif REFindNoCase("[0-9a-z]{3}",mystring)>
hammer time
<cfelse>
nada
</cfif>
I'm using CF 6.1
