so far i can tell these three either dont pay MN fees or pay less then required or run unknown masternode versions as of late :
XxDotRpSDzgyAkx3jHkLZD8YYZRwbcjmmA : getting unpaid blocks with unknown masternode version
XkETHbymbZgkpjHG3f4Ad8osWg3XkPta5L : paying 20% with masternode version 0.11.1.19+
coinminepl : paying the required 37.5% with unknown masternode version (coinminepl's records are a bit weird.. sometimes it shows 0.11.1.19+ and other times it show masternode version unknown)
I know their Maxcoin pool was crapped out their last week; I gave up mining Maxcoin as a result

They may be having problems again, perhaps emailing them 1st would be good idea, before saying they are stealing
