One could see it as a bad thing as the AI is lying on two occasions, and that the letter was sent in bad faith (laziness, automated ads, perhaps even passing off others' content as your own/wording).
In extension, or rather because of the two first points, one could call this a "scam for Tim's time".
The scam in OPs post might just be worse than regular scams, not because it is dangerous, but because it makes us lose trust in others. How hard would it be if you actually happened to be a Nigerian prince who wants to share his wealth? Well, now smaller developers can finally find out!
Haven't read the article yet so please excuse my ignorance, but wouldn't driving the pillars for the foundation into the sediment produce infrasound? And once the turbine is running, it's hard to imagine such a large device to not cause any kind of sub 20Hz vibrations. After all, you can usually hear and sometimes feel them when standing close by the mills on land. (Edit: or, you're really only hearing the ripples propagating along the infrasound wave, or "woosh", of the blades passing the tower. The time^-1^ between two "whoosh"-es being the frequency of this particular infrasound wave.)
Though, whether the infrasound is loud enough to be a problem is questionable.
