Blendle allows no-question refunds, and it seems to be working very well. I think you'd have to do it that way.

For the Bitcoiners, there's the nano-paywall from https://satoshipay.io/ . (I'm part of the team working on this). We're currently trying to integrate fiat payments too, which would make this a browser wallet of sorts that can be used to pay micro-amounts to publishers. Still early days, but think we're on to something with a lot of potential.

Pay a fixed amount every month to a third party that redistribute money to all the articles that you "liked" with a button.

That's the model of Flattr. I have no idea how successful they are though.

I have a Flattr account, but I only use it for regular contributions to a couple of open source projects, since I never see a button anywhere.

Being in the content game, it's because it's totally not worth littering pages for the 5 cents a month it'd make.

I'm hyperbolizing, but even if it were $100/month, it wouldn't be worth the space. What this space needs is someone with deep pockets to subsidize the publisher growth until the critical mass of users is reached.

Micropayments have been the obvious - to me - solution for this problem since I got on the internet in 1997. Still never seen it employed anywhere. Yes, heard of flattr. Never seen a single site that uses it.

I feel like unless it's opt-out per article, you'll forget to click often enough that the price of clicking will have to be high
