How accurate is that Hacked Off poll?

So, yesterday and today i had been seeing tweets about signing the Hackedoff petition , so i thought i would give it a go

I signed in using the name *Adolf Hitler* and the email address *Nazis@hh.com* and then clicked

I demand a Judge-led Inquiry into this Petitionshambles!

Update :

Just signed the Hacked Off petition as Hugh Grant. No check to see if I'm in the UK or not, or if I'm actually called Hugh. #ironclad

I've signed it as Andy Coulson too. Same computer, no checks on duplicate IP address. Oh dear.
