SEGA, or a company acting on the behalf of SEGA, has started issuing copyright takedown notice to people on social media who have been spreading the Persona 6 leaked images adding further confirmation that the images are legitimate and that the game could potentially be unveiled this week. We have the Summer Game Fest happening tomorrow and the Xbox Game Showcase on Sunday, so it could well to be shown at one of these.
“Got a DMCA takedown request by Sega,” wrote X user Dkmariolink, one of those hit by copyright removals. “Not posting it again, but if you know, you know.” IGN has asked Sega for comment.

How does this stuff even leak in the first place? I really do wonder where leakers get their sources from.
Probably someone who leaked stuff online or in a private Discord chat might have been working for the company.
They are being like Nintendo. They took down stuff too because its their right and IPs.
