What nonsense! Have you looked at the last 20 pages? There are buckets of criticism and hate poured out. There are maybe one or two posts per page that have positive or thoughtful content. And you claim that the fanboys of L&P are making this thread unbearable? Purely in terms of the number of posts, they are rather lonely shouters in the desert.
No, there are no rules prohibiting "negative opinion or criticism" and that's a good thing!
But there are also no rules that prohibit positive opinions or criticism.
When I came to this forum, it was overrun by fanboys and people either kept quiet or stopped talking to avoid being attacked by fanboys.
And when those fanboys took over this forum, attacking and ridiculing people, you acted with them, or at least stood by them.
You are not a mediator or an ordinary person.
You were clearly an accomplice at the time.
If you find yourself in a lonely situation, it is the price you pay for your actions, and it is your developer who made you lonely, not the users of this forum.
Your situation will change if you go to a Patreon site or if you ask your developer to create content that people are happy with.
But you probably won't open a Patreon account or ask your developer for such content.
Are the 20+ pages just filled with complaints?
That's the dissatisfaction people feel about this game.
