Probably because they'd potentially be blocking "legitimate" users

It's possible this is just an attempt to limit bot accounts

It could be used to deter users from making multiple accounts. It won't stop determined spammers though.

How is a blocking feature going to help when it's trivial to create a new account?

hueving • Jul 8, 2018 • View on HN

Careful, because of nat that's also a way to ban potential legit users.

slater • Apr 23, 2024 • View on HN

They're back. At this point it might be worthwhile switching off new account registrations for a while?

Did you try rate limiting, shadow banning, ip banning etc?

alecbz • Jun 14, 2023 • View on HN

I imagine there's ways to curtail that (like detecting non-human users).

It probably requires a phone number to limit the amount of bots on the platform.

It's an easy (obviously not perfect) way to have some limit on the number of accounts you create.
