Again, I look at it much like a paper petition. If you get a paper petition that has five signatures of people from one address, you think that it's a family and that's why there are five signatures. If you get a paper petition that has signatures of 300 people from the same address, you think obviously that somebody has just made them up.
I think the clerk already has discretion over that, to be able to say the signatures are invalid. I think the same rationale could be used, but the IP address would essentially tell you the computer. It would act like a home address in some ways.
