A scammer could probably just use a lower tech method (or pay someone in a third world country next to nothing) to type out a draft message.

They don't need a language model. That seems more like Sam trying to sell his brand.

Scammers also tend to focus more on gullible people, rather than someone who has their wits about them.

That's my view, at least.

Any technology can be abused, of course, but it's not worth living in fear of bad people doing bad things.
