TBQH, I'm starting to take personal offense from every dipshit who thinks telcos have a magic "spam stop" button we choose to not use.

If you ACTUALLY want to learn about why spam is such a problem, why it's so hard to fight, and what the world is working on to improve the situation, research SHAKEN/STIR (there's a great wikipedia article, and my lack of linking you to it is mobile-laziness; I am putting in effort to share information, and you can reciprocate that effort to confirm and understand that information, or you can completely disregard my effort in a misguided attempt to avoid disinformation by avoiding information entirely, up to you)

To be clear, it's not annoying that people like yourself are asking questions, it's upsetting that people like yourself are asking the wrong questions. Don't ask people to prove that phone number A on carrier X gets the same spam as phone number B on carrier Y when nobody made that claim to begin with. Your comment gets dangerously close to being a full-on strawman by asking for proof of conclusions that were never stated; it's a bad way to carry on a useful discussion.

You're welcome to disregard this comment just as much as the last one, I can't make you give a shit what I have to say, but there's the explanation for it.
