Protect users from stalking and abuse

[LGro]

Collect and outline stalking protection features, like:

• make it transparent at all times what information is shared with whom
  • allow viewing one's profile from another person's perspective
  • list people or at least groups next to each profile info to indicate with whom it was shared (also even if just previously shared and now stopped but in case the value hasn't changed since)
  • same as above for locations
  • prevent screenshots?
• allow some extent of remote deletion of information (at least of managed or present information)
• no notification when a contact "unshares"
• communicate clearly what realistic expectations are (what can be assumed to be deleted, what not, how far do privacy guarantees extend)

If you have experience with stalking or stalking protection in a relevant context, please help educate the choices made in Coagulate by commenting here or reaching out to a maintainer directly.
