What's the security risk? if a millionaire wants to donate money to make it happen, I'm sure the company he works for would be thrilled to draw up a contract for him that basically says that the money is a donation towards the funding of the game and that they have no rights regarding the game that is made.
Think security risk was the wrong word. Hmm...I think what I'm trying to say is KS vs 'random FB dude' is mismatched on the scale of 'reputable transactions' that you'd allow someone to perform with limited authority.
Let me try and break this down into an example:
-I own a business.
-I allow two employees to seek ways to fund our new project.
-Employee A comes back, shows me the KS website. KS has been in operation for a long time, has a good reputation, is trust worthy, and offers protections for the people involved.
-Employee B comes back and tells me Mr. Mac Scruffles of Scandinavia contacted him on Facebook offering a check of $5M to our project.
-Both Employees have equal 'trust' value and neither have failed me prior.
I'm always going to go with Employee A.
'Random generous benefactor on Facebook' is too much like 'I'm an Arabian Prince and I need you to send me $1000 to cash this huge check, of which you'll get half.'
Sure, it might be a real prince. But odds are you're just wasting your time believing it to be true. The amount of credibility/weight in a company you'd need to engage in negotiations over such a 'risk' is far greater than what you'd need to start a KickStarter, I believe.
