Personally I NEVER want my vouching for or receiving of vouching to be automated - by definition that's not vouching. It never can be.

I can never trust anything but the person with whom I have a history.

I would never drop an endorsement and stand behind it without that history and assurance that I was right.

There are some companies that I would never hire an ex-employee from unless I had two people I've know for a while vouching for them - it's their reputation and our history together that justifying my trust in their endorsement and that can ONLY be an interpersonal relationship as its basis. Anything else is just some random acquaintance or stranger making a claim.

It's ONLY the personal history that enables vouching to work. And it's the EXISTING relationship that is more important than the welfare or benefit of ANY vouchee!

Some things simple DO NOT NEED to be automated and probably SHOULD NOT be.
