Beyhive definitely. Other fan bases have their aggressive stans, but a good chunk of the Hive members are consistently aggressive. You can't say anything even remotely negative about Bey without them going into full dragging mode.
Monsters in their heyday were something else too...
Beyhive, Ive seen some agressive stans before but the majority of the Beyhive are very aggressive and they get really below the belt and nasty at times.
