The problem is it isn't really people doing that. All it takes is one person to set the process running and forget about it. Soon enough all exploitable systems are exploited if the cost of doing so is low enough.
And not only crime. I think it's going to be a lot of people trying to hustle via mass-automated fake-human interaction -- whether it's sales, influencing/advertising, recruiting, dating, or whatever.
And they're being encouraged towards that: even tech companies with reputations to lose are already aggressively offering to take over as someone goes to write an email or text, and proactively "summarizing" the one-to-one human communications of others. But there will actually be demand for one-to-many fake one-on-one interactions, in the hustle culture, and doing it to strangers will seem no worse than what they've already done: corrupting pre-existing interpersonal relationships.
