I don't think we should even be having the discussion about legalities around declaring yourself as an LLC when you're not. I don't think that's going to be helpful, and none of us to my knowledge or lawyers in that specialty. And ultimately, I don't think it matters. none of us are going to sue Don.
The only reason this matters (to me) isn't from a legal perspective, but just from a trust perspective.
They said they were an LLC and they are not
Their website listed on the "press release" didn't exist at the time they sent it.
They used images from Heroforge on their product before removing it after being called out.
Michael continues to say it was untrue that Justin asked for money from Luke to use DHS during Garycon, but Luke has confirmed this is true
They moved their Convention to match GaryCon for what I feel are dubious reasons.
The whole history of June/July with all the untruthful shenanigans they were doing
So all those things above, while most likely all legal (except the Heroforge part), tell me that I don't trust them, and that I don't believe this "threatening anonymous email" is necessarily true. Especially since it was written in the same grammar style as Justin, errors and all.
Discussing the legalities of all this is moot, IMO.
