I guess I'll be the one to start this thread.
More than 2 weeks ago, Nicksasa, the notroll.in pool operator, introduced a bug on his pool that caused some miners to be double-paid for a short period. Rather than correct the issue by identifying exactly who was double-paid and correcting only the balances that were erroneous, Nicksasa decided to instead simply take a flat ~30% from the overall balance of every single user in his pool, whether they were actually mining during the double-payment period or not.
Obviously, this resulted in quite a few people having ridiculous sums of litecoins essentially stolen from their accounts. There are several people on this board claiming losses into the hundreds of litecoins, when they were either not mining at all during the double-payment period, or only mined a small handful of ltc (one user claimed that he mines 5 ltc/day but Nicksasa took 118 ltc from him, for example). I will link the actual thread below. I have a friend that had just over 10 litecoins taken from her account (weeks worth of mining for her!) when she wasn't mining at all during the double-payment period.
On April 10th, Nicksasa finally responded to users, admitting that he did indeed just take a flat percentage from everyone to cover his own mistake. He said that it was true that some people had more taken from them than was fair. He said that he would be putting up a page on his site so that people could submit claims to be reimbursed:
https://bitcointalksearch.org/topic/m.1797285All of that was 2 weeks ago. No page has been put up. Nobody (to my knowledge) has been reimbursed. Nicksasa has stopped communicating on this board, although you can check his profile to see that he is still lurking. There are no messages on notroll.in at all about the incident.
Meanwhile, the notroll.in thread continues to fill up with more accusations of shares not being counted, payouts not working, and other shady stuff. It looks like Nicksasa is content to simply let his pool die a slow death while milking it for as much as he can while the people that don't know about this continue to mine there.
Please give this guy a "scammer" tag so at least the people that see his threads will immediately see that he shouldn't be trusted without having to read through 40+ pages of information.
