    The challenge of having your device solve a nasty PoW that takes minutes would not deter most people: a timer once is better than evil captchas, phone numbers, etc. I don’t understand why they use hCaptcha and not that.

      If one computer can create a single spam account every few minutes, imagine how many total spam accounts could be created by a small farm of computers, in a single day.

        A lot, but farming phone numbers from poor countries is also cheap and Signal sends them insanely expensive SMS. There is no perfect solution, spammers aren’t stupid. Since Signal is centralised they can enforce PoW incrementally if they get reports for spam, I still think it is way better than hCaptcha which is garbage.
