...there were the notorious "phantom shitters" in Flanner from '93-'95 who would literally shit everywhere imaginable. Loafs in the showers, sinks, clothes washers, in take-out boxes in the elevators, on the study lounge desks, stairwells... These guys were technicians. Way too much crap for it to be only one perpetrator.
They came from 10B . . . he is one and the same . . .
