Sure, the typical customer is this semi-professional non-profit organization that need something more "result driven" than change.org when it comes to build its audience (nothing black hat, really).
I'm sure you know your audience very well - it is just that I am missing something.
That may come off as cynical to people, but as a petition-signer, I'd rather get followed up a couple times by an organization actually working on something I care about (and given a path to act a little more on my caring, even if it's 'come to this event' or 'give us money') than followed up indefinitely by change.org, who cannot seem to guess well at all what sort of petitions I'd like to support.
