The opposite - I made a mistake in my first post, my apologies. EbonMask came way later, HalloftheEbonMask was the original faction but for some reason here  on P99 all of the quests I linked give EbonMask NOT HalloftheEbonMask hits. 
 
Basically the NPCs (except Molon and Glazin) are on the classic faction while the faction hits from their quests give non-classic faction. Every quest or mob that gives a + or - EbonMask hit should give HalloftheEbonMask instead. Also, Molon T`plth and Glazin K`Jartan need to be moved to HalloftheEbonMask faction. 
 
I realized the discrepancy when I did Moss Snakes quest dozens of time and saw no changes (while getting +Ebon Mask), then I stumbled upon Molon T`plth and saw he was getting friendlier. So while the faction work I did would benefit from putting everyone on Ebon Mask - the classic solution is, infact, changing the faction hits from Ebon Mask to HalloftheEbonMask and adjusting Molon and Glazin.
