I get like 7-8 spam texts and calls a day from numbers within my own state.
I suspect that something like hashcash or adding some small fee (like $1, that is returned to the spender if the recipient doesn't reply "STOP") would pretty much shut down these spam calls.
Please do not suggest these terrible solutions that make SMS/calls an unreliable transport, when it is just a sybil problem.
