regex for multiple line breakes

[Merlin Morgenstern <merlin_x@xxxxxxxxxxx>]

Hi there,

I am trying to remove multiple linebreakes from a textarea input. 
Spammers tend to insert multiple line breakes. The problem is, that I 
want to allow 2 line breaks so basic formating should be allowed.

I am doing this by regex:
$data[txt] = preg_replace('`[\r\n]+`',"\n",$data[txt]);

I would need a regex that allows \r\n\r\n, but not more than this.

Thank you for any help,

Merlin
