look you obviously don't do grassroots political organising if you're asking such silly questions - this whole thread was about you thinking numberless signal accounts aren't useful - and being more worried about your made up spam boogieman - than the actual threat of fascistic state violence

prepaid sims exist, yes briar exists but it's not viable when people need to communicate over whole city distances (eg for spotting), if the cops can connect your burner to your actual ID at an anti-ICE protest - they can very easily raid your house after the fact - and no they don't even need a warrant due to the extraordinarily powers given to "anti-terror" police forces.

please touch grass and stop being an armchair security expert and let the adults think about applied security in the real world
