It doesn't work. You cannot see any of the signatures nor comments, just the total number of signatures.
Instead, you get the following note:
PetitionOnline.com has temporarily disabled the display of email addresses for signatories who chose to make their address public.We have done this to reduce the spread of harmful new viruses which harvest email addresses from the web cache of infected computers. This will also prevent spammers from harvesting email addresses from this site.
True, it isn't so much fun for us to see, like the other one.
What is funny is that our remarks will be in the delivered petition. If we pollute it enough, they can't use it (not that on-line petitions are worth much, anyway).
The idea we made a DUmmy go through and spend a lot of time editing out our remarks is thanks enough.
