Yesterday I had a 100 pefect reputation and today I got a Red Thumbs Down an it dropped to 60. Can someone explain this?

Why did it dropped so much? And how could 1 thumbs down by 1 player drop it by so much? Now I can't play more than 10 turn based games. This is an unfair system.

Your karma drops if you receive too many red thumbs vs. green thumbs. I don't know how much the drop is, maybe 40%. And I don't know how much is "too many", but when you get the one that breaks the threshold you'll see the sudden drop, it was not one red thumb, it was all the others you received before.

The threshold is if you’re above 10% red thumbs then every new red thumb you get drops you to 60% karma. It’s a dumb system because I find more people give out red thumbs and for illegitimate reasons than people give green thumbs so it’s really difficult to get out of if you get into it. My personal opinion is that the system should change so that red thumbs will only affect that % threshold for a set amount of time before they no longer count against you (the person who thumbed you can keep the red thumb on you but it just doesn’t affect your threshold anymore).

Since you need to give at least one (maybe more) green thumb per (public) red thumb, I don't see how that can happen. Unless I am wrong, misinterpreted/forgot the red thumb restrictions (which I can't find now), or things have changed.
