Last year, after receiving several spam texts from numbers that were registered to Bandwidth.com (which was already difficult to discover), I sent an abuse report. I was not only told that Bandwidth.com couldn't do anything about it (other than forward the report to the reseller), but also they couldn't even tell me who they were reselling services to due to privacy reasons, and did not even know who the end customer was. They advised me to contact the police... To report text message spam.
