there is no "duty" here for anyone. people can choose to be kind enough to others to spread the knowledge they have the best way they can. that is all. there is no obligations in my opinion. people are here to discuss, learn, earn, and increase their overall understanding of bitcoin and sometimes cryptocurrencies in general. they can help keep the forum clean by reporting shitposts, reporting account farmers,... as they are already doing in meta board. but there still isn't any obligations, they are doing it because they want a better forum they enjoy participating in.
