I tried this Telegram feature out some years ago but have it turned off since then. Spammers still find me, overly sexy profiles starting a conversation with a "xyz is 3km away" banner above the chat. One legit person also started a conversation once, they said I appeared as within a few km in a nearby city, so it doesn't seem to be my home address that I'm sharing.<p>Is there a way to find out which location I've been sharing? (I'd be happy to PM someone my phone number if you've already set up this trilateration script.)<p>And secondarily (damage is done now anyway) how to remove this last seen location?
The linked page says Telegram fixed this, but they only say they're now rounding the results. Hasn't this come up previously in other services and rounding is _not_ enough? It seems like it just makes it very slightly less obviously possible but doesn't prevent exploitation.

This is extra interesting given the recent (un?)importance of Telegram in the Ukraine conflict. EFF wrote about it recently here: <a href="https://www.eff.org/deeplinks/2022/03/telegram-harm-reduction-users-russia-and-ukraine" rel="nofollow">https://www.eff.org/deeplinks/2022/03/telegram-harm-reductio...</a>
