How possible that pool is getting donations from unused NMC when NMC are not working since march?
NMC was being mined continuously the whole time. NMC payouts were delayed for a couple of months after the exploit occurred in March, but wizkid patched up the code and everybody got paid in full recently, maybe a month ago? And NMC payouts happen regularly now, AFAIK. At least nobody has asked about it recently.
