When the game first had a Steam page, there were a few people going to the forums to post ragebait because gay furry porn game is an easy target, so the easiest thing to do was just lock down the board. There's generally less shitters/more active global moderation here.
Tbh, everything is an easy target for shitposting nowadays. To be clear, I wasn't trying to convince/force you to open the Steam forum, I was just surprised to see it blocked and curious about the reason behind it, which is completely understandable. As I said, since we can report stuff here, no biggie.
