Not in this instance, I assume. People flagging too much can result in shadowbanning, but perhaps the mods think that flagging posts that might host heated political-religious discussion is ok (even if they don't have such discussion, and even if they are on-topic for HN).
I also don't think there is a way to complain about abusing flags other than emailing the mods; I have no clue about the effectiveness of this complaint.
I have emailed many time over the years. Got a response from dang every single time. Several accounts lost vouching privileges thanks to my emails, among other things — they were vouching clearly guidelines-breaking crap, I drew dang’s attention, and they were penalized. So, if you have a concern, just email.
