Even just verifying a phone number adds a real world cost to

There is certainly a cost for casual users wishing to switch
identities. Both for wannabe trolls & spammers and people that would
have preferred (or for which it would have been wiser) not to use
their main identity for $community.¹ Having them provide their "real"
phone number means they are easier to block, as well as easier to track
and by whatever corporation is going to mint it to... ehm "provide a
more customized experience to you" (even though that might be
undesirable for the user privacy).
I wonder however if that's still the case for "professional" spammers,
as I expect they would be able to buy phone numbers more easily and
cheap than common users. Is it really a hurdle for them or just a minor
annoyance?
When compared to an open system like email, where one can create
"identities" trivially, forcing a spammer to acquire a new phone number
per unique identity is definitely a useful and limiting factor.
While the cost is not all that significant to obtain a new number for an
individual, doing so in bulk will absolutely require a change in
behaviour on the part of spammers.
