They've done this to others, too, so I'm coming forward with this.
This isn't just some personal issue; I only have access to my screenshots because everyone else's stuff gets deleted & you cannot expect everyone to take screenshots of their comments beforehand. There is proof of others getting their comments deleted that aren't mine on their game page and in their other game jam entries. What they are doing is censorship. They are actively suppressing information and fabricating another story entirely by commenting things like, "You're working for someone else" or "You never reviewed our game," then blocking the person and deleting others' comments. It's not just one user's comments; it's anything they don't like, or that will change the story they want others to see. That's why their game's demo has comments spread out so far apart.
Their behavior has attacked the community, and that is why I'm speaking out where I can. They do what I stated above across any platform that enables them to do so.
