Google messages has good spam filtering, but that requires you to use Google messages. Depends if you prefer Google or spam

Make complaints to your congressman's office. Those texts are illegal and should be reported.

Are you responding literally "stop" or are you editorializing like "please stop for the love of Satan"? The former is supposed to be seen by the system and you're supposed yo be automatically unsubscribed. The latter goes to a person and that person may try to engage you. At least, when I've done text-banking, that's how it worked. A less reputable system may try to engage you regardless. If you get sent to a person it's also up to the person to decide if and how they talk to you. If I saw something that made it clear the person didn't want to talk, I would tell the system to unsub them, others might try to be persistent.

Port your number to Google voice. Their spam blocking is great. That and/or get a Pixel. TBH I'm not exactly sure which one is blocking spam calls but I haven't gotten one in years. I only use Google voice for texting though, so that would have to be blocking spam texts.

all of the above.
