How exactly does that prevent spam, vs just using other existing established verification methods like email validation? If the only goal is preventing spam, its overkill, and other web sites who also have to contend with spam don’t use it.
It's trivial to create new accounts and emails to verify those accounts. It is not trivial to get a new phone number since virtual numbers are blocked by the verification process.
Is it just me or does that "comparison" make no sense for this thread. It's mostly comparing vaultwarden to the cloud version of bitwarden, not the self hosted version. It only mentions the self hosted version in passing. It doesn't do anything to help someone choose between vaultwarden and self hosted bitwarden
