I don't think they're shady per se, just spammy. Mine seemed lightly tailored, so I imagine there is a bit of AI going on there. It appears they are a legit cinematographer that has worked on a good number of short films. Seems like it is just marketing spam.
I just noticed Cory Doctorow posted mentioning it. https://bsky.app/profile/doctorow.pluralistic.net/post/3mvcyut5aq22m
