I've been following the comments for a while, so I decided to have a little look into it. I'm not sure what "stuff" you've been looking at, but it seems a few peeps/affiliates/dedicated fanboys here and there are talking (or typing) out of their arses. So here goes;
For starters I'm sure we know what Indiegogo is, a crowdfunding platform. They don't really have any liability at all and you have to agree their terms if you wish to put your sweet, hard earned money down on that shiny new thing that doesn't exist yet.
Do they guarantee perks? No https://support.indiegogo.com/hc/en-us/ar
