The underscore nomap suffix in SSID indicates your desire to opt-out of Wi-Fi positioning systems and, in some cases, mass surveillance. This used to be a not so great blog-post and has since became a hopefully better note to whoever it may concern

_nomap in the end of your SSID will exclude your network from Google, Apple, WiGLE etc. Wikipedia has a more complete list of supporting services.

Microsoft has a separate location services opt-out which uses MAC addresses instead.

Hidden SSID won’t work for opt-out in some of those services. Refer to n/hiddenssid.

Privacy. may point your home directly just by entering the SSID and who knows how many similar services there are. While I have been thinking of this since 2015, there is at least one case where this has been used in 2018:

Legacy from 2015-2016. Used to be part of Microsoft WiFi Sense that shared WiFi networks and passwords to all contacts.

Dear reader, you may be missing a content blocker! 🙀 Please consider installing one to protect yourself, and your close ones, from manipulation and targeted malvertising! Personally I love both Privacy Badger and uBlock Origin (with EFF DNT Policy Allowlist) together, while AdNauseam alone would be more direct protest tool to oppose how the internet is nowadays. Android users may be better served by Rethink while for iOS there is AdGuard. Learn more about targeted advertising! PS. I am sorry if you are already protected and this silly EasyList targeting(?) script doesn't detect that, thank you for taking the steps towards a safer internet! 💜
