It is if the post consistently gets vouched for whenever others stumble across it. Of course if it only got flags then it likely represents a widespread opinion.
There are lots of such asymmetries (although yours isn't very accurate since posts don't get hidden the moment they are flagged) but however the system is tuned, it's still not evidence of abuse. People disagree on what stories belong where and the system may work differently than the way you prefer or assume but neither of these are evidence of abuse. That's not saying there isn't abuse it's just not clear how you reach that.
