No, you're full of shit.
Since you've probably never dealt with death threats, let me introduce you to what it does, and what it means. People get death threats over stupid stuff just because someone out there doesn't like what you do/did, say/said or just despise you for no evident reason but one thing is sure, they hate you. They send threats, through fake mail address, fake accounts, everything they can to reach you and make you feel insecure, scared, and so on. Some people even take it as far as digging around and finding your real name, real address, your friends and family, and contact them. You gotta deal with that how you can, from switching online identity to straight up bringing in the cops into the equation to find the threatening bastard, and even if you deal with him this way, you still gotta usually go through therapy from all the potential trauma he's brought to you and your family. And most of the time, once everything is in the past, and you managed to get back to a somewhat normal life again, the last thing you want is to bring back similar situations or even memories of it.
So yeah, Allegretto here is not "just throwing doxxxing and sent death threats around" nor does he have to share any proof of that cause that would means he has to ask for people that indeed received those to publicly share (or re-share) the information here. And those people does not need to bring that stuff back in their lives just because someone out there is like "proof or that didn't happened" over another game they are not related to.
Like it was said before, if you're not liking something in there, the door is wide open. No one is asking you to come here, to play that game or even read and comment on the discussion if you're not liking what you're seeing.
