Personally, what I've noticed is that they are in an echo chamber and do not allow for people to have differing opinions. Because of the downvote and upvotes, they can just downvote anyone who disagrees with the general sentiment and send them to straight to reddit karma hell. On the FRAF forums, the mods have not deleted any posts and have let everyone talk about it however they want so long as nobody resorts to serious threats or insults.
That, and the subreddit was already full of people who didn't even actually like Beyond Canon or the stuff after the comic ended so any news about this place is just inundated by the whole "I hate future Homestuck stuff!! I think all future homestuck related things should just die bc it's bad and I hate it even if there are people who still like it!!" coupled with the general idea that anyone who disagrees with them must be some brainwashed Hussie defender who just looooooves hussie so much.
I have started all of my posts with the sentiment of "I agree with Gio and think that legal abuse is bad" and even made a whole thread on this website saying as such, but I still get people from those same threads yelling at me, pointing fingers at me, and childishly calling me names or insinuating that I must be some kind of Hussiebot who loves the guy sooooo much. Lol. Lmao even.
I mean, I've had people on this forum accuse me of being stupid because clearly I didn't read the posts while they ignore and put words in my mouth that I never said. I don't think I have actually seen anyone on this website say "Andrew Hussie did nothing wrong here" either, but everyone else outside of this forum is just convinced that's the sentiment all of us neutral grounders share.
