Yeah, along the lines of what Stray Electron was saying:
Ask, like for the U.S. in my case, what's the recent history, Justice Dept. et. al. ?
If answer is that there haven't been ANY prosecutions or investigations of note in, say the last 5 years, then you could continue along that line, asking about complaints filed, or any other indicators that SHOULD warrent some government agency to do at least maybe a cursury look...THEN its time for sounding an alarm.
Notice how far I've tried to lean, in favor of a simple, non-hysterical explanation. Partially because that some big agency like that has been created in the first place, often in response to existing abuses.
I do know for sure, that telecom services regularly scan the MMS system text messages,
as I've had occasional service 'glitches', after texting local Cannabis dispensaries (lol).
With communication to a legal business, like that, I insisted that the telecom provider reinstate my account. But it did happen, and many folks would not have been as firm as I had been. (Heck, I don't know what they would do...maybe change the service provider).
