Look at you getting all defensive about it, not even knowing me. I'm actually an AV-specialist and doing my bachelor in communication multimedia design right now. It was more of an advice for non-professionals, but you couldn't know that. I don't immediately consider people discussing their work via insta DM professionals, so that is why I assumed they weren't professionals. And this is an excellent solution for non-professionals, even for professionals. Where I'm from clients actually respect the choices professionals make in discussing their work and all. Maybe it's different where you are from.

Maybe calm down for a bit and don't get so aggressive with people.
