@bonifartius change your said from MyFancyWiFI to MyFancyWiFI_nomap. The "_nomap" suffix excludes it from Google's geolocation database. Simple as that :)
@ThatCrazyDude will end up in databases nonetheless ;)
@bonifartius well, yeah, I'm sure, but it won't be searchable for people without elevated privileges
@bonifartius and if you want to go full tinfoil hat on it, there's a way for that too. You get a router you can flash OpenWrt on, you type in a little bash script that will periodically change your WiFi's BSSID to a random value, you include it in crontab and there you have it. Devices you use don't give a shit about the mac address. That's why roaming works ;)
@ThatCrazyDude that is probably a good idea. together with a vendor default ssid. regarding _nomap see attached screenshot :P
