Sorry to hear what you went through. There are bound to be outlier events, but it's not as likely to be permanent though, as voters can be influenced as long as they can be reasoned with. I'd be all ears if there's a better solution. Without the current implementation, crude as it may be, we end up with a totally broken platform across the board, at least from my pov. And it's capped at 25%, so it'd take 2 good actors to counteract each mistreatment on the same level of SP, which is doable. And it's not opening a huge door for abuse like you're claiming, as it's too weak for any collusive downvoting (in a way that it can squeeze out the reward pool overwhelmingly for profit).
