I still think that depends on how devious they are and how gullible you are. If you send them an IOU for $100 which doesn’t reference the original debt (the slight of hand I talked about earlier) then you are indeed responsible for that IOU.

Nope. Contracts require consideration to be valid.

If I send you or anyone else an IOU out the the blue, there is nothing you can do to collect it.
