@Dang: Please explain why HN tolerates/allows flagging without having an explanation per flag that’s traceable to guidelines system has logged the related user as having been notified of prior?
As is, to me, I understand balance of HN, having too many rules, injecting rules/systems that upset the feel of HN, but I feel like users abusing flags is toxic to the spirit of HN and if any user is found to be abusing flags they should be ban from being allowed to use flags and disputing flags should be possible; if a user repeatedly falsely disputes flags, they should be ban.
The secret is not to let it bother you. At the end of the day your karma ratings here are just "internet points" and flagging or downvoting are just people proclaiming that "Someone is wrong on the internet!". It really is no different to Twitter or Reddit, in that regard. We just like to delude ourselves we're a cut above those kind of sites.
