Voted, even if the options sucks. To loose 50% of all rewards for 1 bad flip and 100% for 2 or more flips. A fair punishment will be to loose the reward for the reported flip not for all flips made, further more for Invites and Validation. What have to do a bad flip with the invite reward, or the validation?!
Based on DNA price and flip rewards there is currently 1.5$ per good flip. This is way too less to convince majority of network to do good flips. If it would be like you posted than we would see 90% shitty flips.
50% down after 1 and 100% down after 2 is a fair deal.
Of course...
I don't know who you are but it seems that you are taking the side of the project each and every time even if something is not OK you will say it is, like the example above. Again: what have to do the flips made with the invitation rewards. If I make 2 bad flips I loose the Invite reward, for you is fair

)) Let's assume you are a seller at work: If he don't fulfill your task of selling at least 6 products/ month and you sell only 4, you won't loose your commission only, you won't get your salary either. You would say to your boss: "shrouds fair to me"?. Then let's make things "better" why we don't cut the ability of mining also if you make 3 bad flips, and if you make 4 you owe the Idena network some amount of DNA. Why not?! Let's do it!
In your opinion everything that Idena devs benefit from it is perfect, everything is OK, everything is fair which leads me to the thinking you are one of the devs or some paid shill and I'm done talking to you.
