Apparently they were trying to do this here, but a bunch of emails wouldn't cut it. I can actually understand that.
However, there should be a channel for companies to pursue to expedite the process. If I were the Apparent Software, I would send a letter from an attorney- perhaps an affidavit- testifying to what I was trying to do. This would at least take PayPal off the legal hook for anything they are trying to do.
And it's a lesson for all of us. If we want to partner like this, we have to make it easy for our "silent" partners (PayPal, Google Checkout, Amazon-- they are all in the same boat here) to play along. I'm grateful to the blogger for posting: this problem wouldn't have occurred to me.
