Excellent work!! I want to contribute.
My question is: What happens if a thread lives more than 7 days? After that the upvotes are not rewarded :/ ... maybe the solution is to create a new post, but make it transparent for mangosteem showing it as a single thread... what do you think?
It will be amazing with private chats. Then the common people will see encrypted messages and the group will have a key to see them. Since everybody can comment mangosteem must filter the garbage, that is, only show messages with the correct encryption.
Upvote and resteem!
