But Moore ignored the pre-match distraction to steer his side to a welcome point.
Two goals in three minutes left the sides deadlocked at half time after a lively first period.
Alan Lee might have done better for the home side after five minutes but his shot was straight at keeper Jason Brown after Darren Garner's neat throughball.
And only a joint challenge by Chris Swailes and Mike Pollitt at the other end prevented Guy Ipoua scoring as he beat the offside trap.
But Rotherham were in front after 13 minutes when Chris Sedgwick drilled a low cross from the right and Barry Ashby could only steer it past his own keeper as he tried to clear.
Three minutes later Martin McIntosh came close to a second but his downward header hit the post after Garner's free kick.
Gillingham drew level seconds later when Ipoua whipped in a cross after Paul Smith's long ball forward and Rod Wallace was perfectly positioned to tuck away a close-range shot.
A tremendous save from Brown denied Darren Byfield a spectacular Rotherham goal after 33 minutes when he tipped it round before McIntosh was wide with another header.
Soon after the restart Lee made the wrong choice and headed wide when a shot was the better option before Paul Warne blazed over another attempt.
And a spell of pressure midway through the half failed to net Rotherham a goal when a McIntosh header brought a super save from Brown and John Mullin lifted a shot over.
Gillingham's best chance of a winner came when Ipoua broke free in the 79th minute but shot at Pollitt
