Idea: Put free WiFi hotspots in homeless areas (SSID: AskIzzy) that go directly to (and are limited to) your site when the browser launches. Remember that people often have phones but are out of data/minutes when they need help the most.
My only issues with free wireless hotspots is that they tend to be unencrypted which can be dangerous, however if you're in need of assistance this might be worth the risk.
If you're interested in what kind of access homeless and at-risk people have to the internet in Australia this is quite a useful paper: https://accan.org.au/files/Grants/homelessandconnected/Homel...
*Edit: Also we have free wifi if you're near our office building or the near by train station which is an area with a lot of homeless people, from your idea around the SSID name - we'll do that here and spin it up this morning - so thanks for that!
