The original post by @spujb@lemmy.cafe was a woman wearing a shirt that says "Italians do it better". Someone asked what they do, and drag explained the joke as best as drag understood the intention, though drag disagrees that Luigi killed that CEO. It's not a call for violence, it's an explanation of a joke. Other people interpreted the joke the same way.
Less than an hour later, Flying Squid banned drag for that explanation, and for saying Luigi is not guilty. According to Flying Squid, referencing the CEO shooter case and saying Luigi didn't do it is a call for violence. Expressing support for Luigi Mangione is a bannable offense on LemmyShitpost.
EDIT: The Picard Maneuver responded to drag's appeal and reversed the ban. Drag will be deleting this post as it is no longer relevant to the current state of affairs on Lemmy Shitpost.
That's not even close to the worst shit that mod does. For example, they'll personally attack you then call in a mod to ban you for personal attacks.
But, they're never sanctioned. It's good that you've created documentation. But, nothing will happen until he picks on the wrong person.
He's also easy to dox.
