There is currently a bug in our reputation system that is improperly rewarding/demeriting some actions. Basically, we accidentally reversed a couple of things so that in some cases negative actions are increasing someone's reputation and, conversely, positive actions are hurting someone's reputation. That's not good.
This is not impacting everyone, because it is only a certain part of the reputation formula that is working improperly, but it's obviously a pretty major bug.
Of course, we are not enforcing a "Low Rep" status currently, so no one is being harmed by this bug, other than that their Reputation Scores are not accurate.
We plan to fix that sometime next month, when we release our member certification (aka, "KYC") program.
We've also been making some improvements to the overall reputation formula and those changes will be rolled out concurrently with the bug fix next month, as well. I'll go into more details about those changes once we get closer to that release.
