Ask HN: Prevent bots without annoying users

1 pointgregw1341 comment

Does anyone have a good idea of how easy it is to get around these security measures, for motivated users that want to make 50+ fake accounts:

1) cloudflare 2) captcha 3) requiring unique phone number upon account sign up

I'm considering requiring unique phone numbers but am concerned that will stop too many legitimate users from signing up.

Everyone has a unique phone number. Are you looking to have them sign up multiple times with the same number?

You can also require an email address as well if you prefer.

It's definitely going overboard, but I've personally never experienced bots really signing up for anything I've made.

Sounds like you have a great product that bots can take advantage of if you have that many signing up.
