I'm sure it is a genuine issue. However if they are going to use a site like that to host their petitions they still should have included information as to the date signatures are needed by, contact info for the person organizing the petition, age requirement if needed for minor children, who specifically will be recieving the petition, and an alternative method for signing it (ie: snail mail).

Those are petition basics whether online or done door to door in person. I posted that info here so people would be well informed petition signers. I'm not saying it's not a worthy cause, I've just seen too many worthless petitions that I tend to be very cautious about them.
