You won't be able to find a thread without a reckless post.
It means that a dev capable focuses on the fans and constructive opinions and ignores the rest, but anyone should act in this way.
So my considerations are referred to, even if it was understood, to all useful people and actions.
I repeat, for the rest there are no alternatives, only not to reply if you don't want to waste time.
What you actually said, was:
For me, it means that everyone is useful here, no one excluded and everyone has the same rights to express their opinions
You specifically stated that "everyone is useful here, no one excluded". Which was then proven incorrect.
So you're now saying that only useful posts are, um, useful?

Thanks for that brainwave.

But, who defines what is "useful", in your personal system?
I'm sure different people will have differing views on what constitutes "usefulness".
What is useful to one, may be useless to another.
Does your definition match what others choose to define it as? Or is this simply an undefined, subjective opinion of what is useful?
Some of the people making illegitimate complaints will feel justified and valid in doing so.
Some require having their error proven, to show that it was not legitimate.
Some are just trolls, posting purposefully antagonistic comments, hoping to get some attention.
It can be a fine line, discerning between them.
