I like the way you describe your process. As the person who made the stylometry thing that made the rounds a while back, I would say the best thing you can do on that front is to either get a "paraphraser" like ChatGPT/translators or just write less. Also, there's a site called smspva.com and a lot of sites like it where you can rent "real" phone numbers and they take every payment method under the sun. Depending on the country a phone number to receive an OpenAI confirmation code is about $0.50, most less popular services are like $0.10-$0.20.
