having to pay

Yup. Looks like 'get a limited access or pay'. A bad beginning for a new account.

What are your thoughts about an inviting block ("Get Paid for Your Content" or anything else) on each post page for unregistered visitors? Too much?

i would like a sort of custom url like https://peakd.com/hive-197333/@x-rain/hiveposh-weekly-13&src=web2

so that the frontend knows that the user comes from a web2 social and offers a different layout ("Get Paid for Your Content" looks good) and to registr something easier possibly redirect to ocdb on boarding
