Subject: Re: [nycphp-talk] User Input Data scrubbing

does anyone know where I can find a list of sample MALICIOUS data that
i can input into my forms to see how the code reacts?
i'm not looking for any automation or program, just the actual sample
data.  i'm trying to do QA on my code.

any help would be greatly appreciated. thanks.
