when the title for 200 karma came to the game sevenops said you lose 2 karma if report is falseOnly when your report has been rejected, you lost karma, at least it used to work like that. Maybe they've disabled it, so i think this is not a bug
/karmaOh i didnt know about this, so sorry!
Edit: what i have said is still relevant: maybe your reports are just deleted, not rejected, because they dont have any information about the report, so your karma points are not affected. Or simply you just dont get any visual feedback when they are decreased, just like you cant see the amount of karma points you have
