Além disso, o título mais longo do Mapa do Maroto especifica:
Messrs Moony, Wormtail, Padfoot and Prongs Purveyors of Aids to Magical Mischief-Makers are proud to present THE MARAUDER’S MAP.
Obviamente, para serem criadores de itens mágicos indutores de travessuras, eles podem ser presumidos como criadores de travessuras.
Além disso, sabemos que pelo menos James e Sirius se envolveram em provocações e intimidações de Severus Snape:
Muitas vezes, uma brincadeira é apenas bullying para o prazer de si ou dos outros, o que é claramente mostrado na cena acima.
Snape’s wand flew twelve feet into the air and fell with a little thud in the grass behind him. Sirius let out a bark of laughter.
'Impedimenta!' he said, pointing his wand at Snape, who was knocked off his feet halfway through a dive towards his own fallen wand.
Students all around had turned to watch. Some of them had got to their feet and were edging nearer. Some looked apprehensive, others entertained.
‘How’d the exam go, Snivelly?’ said James.
‘I was watching him, his nose was touching the parchment,’ said Sirius viciously. ‘There’ll be great grease marks all over it, they won’t be able to read a word.’
Several people watching laughed; Snape was clearly unpopular. Wormtail sniggered shrilly. Snape was trying to get up, but the jinx was still operating on him; he was struggling, as though bound by invisible ropes.
