(For more information about debt collection, I'd recommend https://www.consumerfinance.gov/consumer-tools/debt-collecti... )
Even if you improve collection practices a tenth of one percent, however, you're still talking big money so I see the appeal of the market size and any potential improvement.
thats the only thing i can imagine is going to come of this
As far as the legal requirements, I believe in the US it's permissible for debt collectors to contact friends/family in order to get in touch with the debtor, but there are certain limitations (like they're not supposed to disclose the amount of the debt, etc).
I think you're right about the practicality issue - I doubt twitter or any other network would want anyone using their platform for that type of activity.

This sounds like it could be bad for consumers. I hope it doesn't lead to people getting shamed on social media for failing to answer bill collector's phone calls - their site is pretty vague about how it works so I'm not sure.
Just another reason to delete your social media accounts.
I think it's a good business idea though.
