I contribute my grain of sand by reporting every single spam SMS that I get . I know those are much harder to spoof so its valuable when they get reported.

This is a nice little resource for quick reporting that an HNer put together recently. I have the abuse report email templated now, so all it takes is 2 minutes to report every new one.

Shout out to Telnyx staff for actually processing my requests with a reasonable SLA. Your CS team should be the industry norm.
