* Author: Michael Vogel <https://pirati.ca/profile/heluecht>
*
* @todo
* Piece of cake?
* - Process facets
* - create facets
*
* Possible but less important:
* - Block, unblock, mute and unmute contacts
*
* Need inspiration:
* - alternate link for contacts
* - plink for posts
* Nice to have:
* - Probing for contacts
*
* Need more information:
* - only fetch new posts
* - detect incoming reshares
* - detect contact relations
* - receive likes
* - follow contacts
* - unfollow contacts
*
* Possible but less important:
* - Block contacts
* - unblock contacts
* - mute contacts
* - unmute contacts
