Paying 1 satoshi for one post is not high amount of money, it is not even 0,01 $. You could purchase even for receiving 1 $ at coinbase the cobboy credits using bitcoin ln which is not also a fortune even for low budget earners. If post is for example 0,05 $ cost or 0,03 $ then it will discourage someone to contribute. Some platforms are up to 14 satoshis but it is not big amount of money. Most of them are replying and not making new threads.
