On Fanvue, you can customize how users view content behind a paywall. You can choose to display posts as blurred, giving fans a teaser and encouraging them to purchase, or completely blacked out so they can't see anything. Note that subscribers and followers can still see post captions.
To enable or disable blurred posts:
Go to Settings > Creator Settings > Profile and Intro Video
Toggle Blur Preview Images on or off
That's it!
