I've consumed lots of random media from many WhatsApp and Telegram groups. I've lost track of lots of it in the stream of information. That stuff doesn't get indexed on Google. The media narrative is tightly controlled, ministers claimed things were under control on TV whilst us on the ground knew this was false. Zello has also been extremely useful for community security. But trust has been an issue because of the open nature of these platforms.
I've been trying for this whole week to come up with tech solutions to this, but there are also social issues technology alone cannot overcome. Eg: Community members organised in adhoc security patrol groups engaged in friendly fire because they did not know they were friendlies. A telegram bot to query registration plates makes sense...but that leads us back to apartheidesque access control (no!) and the issue of trusting the entity that controls the db.
This is the best reference I could find of it in 'mainstream' (News24) media: https://youtu.be/Jq14RiZyJRA?t=3767
