That's precisely the point. Infiltrate me and a group of other people that have nothing going on, as long as I'm wasting your time I'm doing my part in protecting a tiny bit those who lack freedom.
Problem is, you essentially can’t trust people. Not even in a personal “do I know this person” way. But fundamentally people are squishy. If you squish them too much, they’ll do things they never wanted to do. That unfortunately is why groups greater than 1 are a weak spot.
In your scenario, you’ll never know if the last person increments an ID somewhere or did some other activity that adds compromises the chain.
Every person you swap hardware with is a chain leading back to you.
It also becomes tricky to convince someone to lend you their phone in my country since ID cards are required to register any SIM cards.
As someone else above said, adding more people makes the rope (your opsec) weaker.
People generally can't be trusted once their self-preservation instinct kicks in. How sure are you the other guy you trusted enough to put them in your opsec isn't going to sing on you when their balls are gently fondled by LE agents.
Your ISMI (aka your sim card) is going to be sent alongside your IMEI, which makes that type of identity "borrowing" pointless because the carrier can see right through it. wifi mac addresses can be easily spoofed without swapping hardware. Overall I don't see much value in swapping hardware.
Different users of one device muddle location, patterns and data being transferred. This is the usefulness.
I'm lucky enough not to live a pretty vanilla life and so do my peers. Please investigate and waste time and resources in tracking down the most boring and uninteresting (on a political and criminal level) persons you could ever snoop on.
again, once you pay for it, even with cash, they can track you down(though it may take a while). It's trivially easy to see where a given # is, so once they know the phone #, they can pretty easily find out who has it in their possession, by just showing up and seeing who has it in their hand.
Not to say there isn't SOME anonymity by paying cash for a burner phone, but it's not even remotely fool-proof for anyone really wanting to figure out who you are.
yeah running 1 or 2 of your own Tor nodes seems to be pretty ideal. One of which being an exit node. Connecting to that is the move.
providing an obfs4 bridge seems good too
but I really wish there was a docker container for all this, the documentation is all over the place, most of it is just on forums that can only be accessed on Tor and those forums have unreliable uptime, it is really discouraging but it seems like there are some very competent people that are so comfortable doing this that one could just assume they all have this greater level of OPSEC and infrastructure
But if they can trace back all the activity pertaining to a case they can show strongly though not conclusively that you were probably the source? Also as long as they can prove that you constructed the setup you also start looking guilty as hell..
Use TOR for menial stuff to create background noise
Regularly trade laptops and phones with like-minded individuals
Assume you've been breached and that the government has full attention to you
Be as paranoid as possible, any step towards lack of freedom for the sake of convenience is unretracheable
