It's an idea, not a solution. So far, I got @tipu interested as he's already halfway there. Since he's still at it, there might be more viability than we think in expanding the tipping service to support fiat contributions from readers who aren't on steemit.
It's funny that I saw your reply at the time I did. I just woke up to a successful kickstarter campaign by a friend who has a local publishing company for scifi and fantasy translations. The kickstart wasn't doing too great all month, and he was about $2,000 away from his goal 24 hours before the end. He was bitching about it wildly on twitter, and an old acquaintance came to the rescue. Said acquaintance? Neil Fucking Gaiman. So Neil offered a kickstarter reward - his own copy of a special edition of Stardust. It sold for $4,000 or so within a few hours.
My point? Kindness exists. You can build a commercial service on kindness, and people will surprise you.
It seems to me, that steemit member who wanted to could "sign up" to be "available voters",,,, the guest form FB would click the "external vote" button and they would be taken to PayPal were they would be charged some price per vote (based on some reality of steemit voting and costs that i'm completely ignorant to) and that could be received by the private paypal account of the next "signed up" steemit member. If the outsider wanted to give more up votes they could repeat the process, this time paying to the next "signed up" steemit member in line. Obviously the signed up steemit member makes the "up vote" (maybe signed up member would have to meet a requiremnet of a minimum SP so that the vote counts,,,, or the program could match a desired "power level" that the FB person wanted with a signed up voter with the correct SP.
I don't know,,, but I think its a great idea,,, and if its PRIVATE paypal to paypal the regulators cant say or do shit,,,,, Just a thought.
I'm not an active programmer,,, and am very new to steemit,,,, wouldn't know where to begin,,, but I'm sure it could be done.
