This is the least of my concerns with Kickstarter. It’s so trivial to completely scam an entirely fake campaign, with zero repercussions, that no one should take this site seriously at all. I say this as someone who has backed a campaign that posted updates and even claimed that shipments were out while all the comments were the same: I received nothing.
I think nobody is concerned about this because most campaigns just deliver what they promised.
I think kickstarter is gonna have (or maybe already has?) a scam problem due to the rise of AI.
I've contributed to about 7 campaigns; only one didn't work out. But the person running it actually refunded me fully (about 200$) after 3 or 4 years of very occasional updates.
