Uh, yes there is, by the inherent nature of how addresses (i.e. public identifiers) work.
An IP address, email address, physical address, etc, is a mechanism to have a string of text, become a unique identifier for something, so that you can just share that piece of text to refer to it.
Once you give out that piece of text, you no longer have control of it. I can give it to someone and then someone else could ask them about it, and they pass it on, and now I have no idea who has this unique identifier that represents me anywhere out there in the world. I can ask the first person to update their records but I have no guarantee that they’ll do it successfully or that they’ll remember every single person who they gave it out to you update.
By the very nature of being an identity provider, you are inherently offering your users something that they should be able to fully own in perpetuity. In those circumstances, it’s problematic if an identity provider insists that you always have to pay for its services, just to have communication from your old identity forwarded.
Lol did it solve anything though?
If you actually watch the full episode, the timeline of events is:
Kinda feels like the whole GIMP escapade was just a waste of everyone’s time and all it took to solve the case was basic police work in terms of interviewing people who saw her last. By the time they tried GIMP they already had a prime missing person that they thought it was, and they wouldn’t have had to if they just went to a second DNA lab immediately.
