The major difference is that it may force the current scam which seems to rely partially on getting people to download and click the last page and partially on a scammer network to do this for each other to move entirely to scamming real people to click the last page.

That said, that's not a good reason in my mind, since we shouldn't be afraid of stopping abuse just because we are afraid it will shift to another area, as it's still progress. I retract that specific example (but I think the others are worth thinking about).
