It just seems surprising that no one seems to actually investigate and prosecute those who make death threats online. I'm not saying that people should lose anonymity online in the vast majority of cases, but when people are making death threats and even coordinating and conspiring to harass someone with death threats and potential real-world harm, it seems like police should be getting warrants for things like IP addresses, device IDs, browser fingerprints, phone numbers, and other anti-spam information that sites are using.
I know some people know a lot about how they're being tracked online, but most people don't. If there are hundreds of people posting death threats, most probably aren't hiding who they are well. Prosecuting even a few seems like it would deter a lot more. How confident are you that you aren't leaving a trail? I'm not saying that people should be generally worried about leaving a trail, but when it comes to death threats that can turn into actual murder people seem oddly confident that no one will track them down - despite all we know about how good platforms like Facebook are at figuring out who we really are.
It's not like police aren't asking for huge warrants from people like Google. Google has said that they're getting a huge number of geofence warrants - "hey, give us a list of everyone who has been in this geographic area." That seems way more problematic than "hey, there has been a criminal assault (death threat) and we want all identifying information you have on this account that committed the assault." Again, I'm not saying that the person behind the account should instantly be found guilty (accounts can be hacked and such), but it seems to offer a much more precise avenue of getting to bad people than a geofence warrant with a lot fewer privacy implications.
> I contacted Facebook. The best the company could suggest was to block trolls from future posts
Facebook knows who these people are. They could ban them from FB/WhatsApp/Instagram. It's weird because they seem like the type of thing you'd want to ban for SPAM/harrassment.
It seems weird that the response from sites and police seems to be: there's nothing we can do. These are the same sites that figure out things voting rings for anti-spam reasons. These are the same police that vigorously want to prosecute someone for stealing $20. But when it comes to death threats (that can turn into actual murder), they seem to think "that seems like a minor inconvenience compared to SPAM or someone stealing $20."
