So it wasn't really as fair as you marketed it after all? Your post seems legit and you reacted quick.

In 2016 I built a Loto website for STEEM (I think it was the first gambling app), and even Dan Larimer asked me to use the block hashes for 'provably fair' verification (see https://steempeak.com/steemloto/@heimindanger/introducing-the-first-steem-dollars-lottery-only-usd0-01-sbd-per-ticket) so I guess people cannot blame you so much for doing this. But obviously Dan Larimer was trying to cheat too, he knew these hashes are manipulable (PoW was fast and easy in Steem back then)

My main question is how do you feel about lying to your customers about having a 'provably exploitable' instead of 'provably fair' pseudo random number generation algorithm? And how bad do you think this would have been if your userbase was 100x bigger than what it is today?

Finally, who was the witnesses who controlled the hashes of the blocks where the attack happened, you should blame him and try to get him unvoted out of top 20?
