Well my last tweet didn’t seem very bot-like to me; algorithms might have tagged me as a racist troll though (ironically). Not sure what twitter is picking up.
There’s no evidence that deleting your phone number on your account deletes your phone number from their records. It is in the financial interest of twitter to use your phone number to increase their ad revenue. Furthermore, they routinely capture phone numbers from third party apps for the purposes of doing exactly this. They value this information.
What can be done with a phone number? As of May 17 researchers at Carnegie Mellon University documented that California based tracking firm LocationSmart permited real time location lookups for anyone who visited their website and wanted to try their product. Ok, they’ve disabled the demo now. But aggregation firms like them haven’t gone out of business. Yet.
On June 18, Krebs Security reported that AT&T, Sprint and Verizon claim they are terminating location data sharing agreements with third parties. That’s nice. Later there was a tweet by T-Mobile. That said I remain dubious about announcements that can later be reversed. It’s easy to imagine this sort of thing being handled by legislation. That hasn’t happened yet.
Tech security reporter Brian Krebs:
[INDENT] Blake Reid, an associate clinical professor at the University of Colorado School of Law, said the entire mobile location-sharing debacle shows the futility of transitive trust.
“The carriers basically have arrangements with these location aggregators that contractually say, ‘You agree not to use this access we provide you without getting customer consent’,” Reid said. “Then that aggregator has a relationship with another aggregator, and so on. So what we then have is this long chain of trust where no one has ever consented to the provision of the location information, and yet it ends up getting disclosed anyhow.”
Curious how we got here and what Congress or federal regulators might do about the current situation? Check out last month’s story, Why Is Your Location Data No Longer Private. [/INDENT]
