Most Damaging Social Media Mistake for Filmmakers?

Hey everyone,

I'm Omar, a Steadicam op usually working with an ALEXA 35 or sometimes an AMIRA, and diving into the social media side of things for an upcoming short I shot on a C70. I've been trying to brainstorm a campaign, pulling footage from our rushes, behind-the-scenes stuff shot on a Pocket Cinema Camera 6K G2, and some interviews we did under a couple of amaran 150c lights.

I've seen so many lists of social media no-nos for filmmakers, everything from butchering content repurposing to completely ignoring UGC licensing, which I know is huge. But it got me thinking. Out of all the potential blunders, what's the single most damaging and difficult-to-recover-from mistake a filmmaker can make in their social media campaign? What's the one that really sinks a project or their reputation in a way that's almost impossible to come back from?

Thanks for any insights!
