Having been on the purchasing end for wholesale marketing SMS I can tell you most of sales people will suggest the 'correct' way and happily sell things that let you do it the 'wrong' way.
I only recommend responding STOP to short codes since there's more investment and vetting on getting a short code. Carriers will intercept the request for TFN/local numbers sometimes but I don't really trust it. These numbers are all going to be spammers buying pools of numbers to churn and burn. They'll just import their list into a new account if it unsubs.
Oh and btw, it's actually easier now as a spammer to tell when numbers get burned. A few years back when the CTIA handover on regs happened (and sending costs went up) the carriers finally started to respond with the delivery status of the sent messages. Before this they didn't respond and you only knew your provider delivered the messages to the carrier, not whether the carrier delivered them to the handset.
So, I made a "Plane Above Me" app that listens to airplane sound. Once detected, it polls data from flight APIs and read out the flight info and aircraft data.
In other words, it's my little "Flight Announcer".
I'm not old enough to be keeping an eye on the numbers, but it looks like ~$450 / month for hospital (free) + doctor (subsidized) + prescription (pay).
DemDex "captures behavioral data on behalf of Websites and advertisers and stores it in a 'behavioral data bank.'"
uMatrix blocks it for me, but this shit could harvest banking credentials??
My guess is that comma-separated lists tend to be a feature of text that is attempting to be either comprehensively expository—listing all the possibilities, all the relevant factors, etc.—or persuasive—listing a compelling set of examples or other supporting arguments so that at least one of them is likely to convince the reader.
I find myself constantly editing my natural writing style to sound less like an AI so this discussion of em dash use is a sore spot. Personally I think many people overrate their ability to recognize AI-generated copy without a good feedback loop of their own false positives (or false negatives for that matter).
