The publication will remain forever in the blockchain. If what you want is to appreciate the value of the content, you can always do it.

Now let's talk about payment. Increasing the payment window will not allow you to earn significantly greater rewards. We can compare with the Publish0x platform, there the payment period for publications does not have an expiration date. But this does not imply greater rewards. Most users look for the latest posts to tip. When publications have more than three days, they practically no longer receive payment.

This 7-day window allows us to enjoy "fresh" content, also meets the brain proof for participants.

Resteem a post should not generate payment. This will bring more abuse problems to our platform, which will later become, surely, in more censorship.
