Apparently, I've been flag banned again, after a very small amount of time.
This time it's because I flagged this question, which is a wonderful example of rudeness (I'm considering the question and the comments as a whole). Let me just quote a few parts:
After 3 years, i come back for using linux and its still suck with drivers
But its really stupid when you can get one laptop work properly
How the hell itsn't the error message?
end users don't have time for this stupid s**t.
Can you read? The question is very clear
Now. The importance of the Be nice policy and the same concept expressed in the Ubuntu Code of Conduct is a fact and not something debatable. Even if it was, it has already been discussed on meta. I really hope there is no disagreement here.
It seems to me that lately my flags get denied a lot more than before, even if I never changed the criteria I use for flagging stuff. I could just stop flagging altogether and go on with other contributions (of course with much less engagement than before) but I prefer to understand the reasons behind this and especially why a flag for objectively nonconstructive behavior has been declined.
