The online campaign #TakeDownJulienBlanc quickly gathered steam and several hotels and businesses cancelled bookings, forcing Blanc to stage alternate events.
On Thursday night, Blanc did not show at an event on a boat on the Yarra River and instead sent another Real Social Dynamics employee, "Maximilian", to hold the seminar.
Journalist Asher Wolf told BuzzFeed News the men eventually got on to the boat as protesters chanted and tried to board the vessel. "It was intense and surreal," Wolf said.
Police arrived and kept protestors from boarding the vessel. Despite criticism that the officers were protecting men who advocate abuse towards women, "the police did their job," Wolf said.
Herald Sun journalist Tom Minear spoke to Maximilian, who said it was "sad" the seminar had been shut down.
There was an explosion of praise online, where the #TakeDownJulienBlanc campaign had started.
The Bayview on the Park hotel also cancelled the booking Blanc made to stay there, writing on its Facebook page: "Bayview on the Park does not condone assault and abuse of women."
UPDATE 1830AEST: Immigration Minister Scott Morrison intervened in the case and deported Julien Blanc.
"This guy wasn't pushing forward political ideas, he was putting a view that was derogatory to women and that's just something that our values abhor in this country," Mr Morrison told Sky News.
The case has broken new ground for authorities.
"Labelling women as objects and actively promoting the abuse of women degrades the dignity of our whole community," Victorian Police Commissioner Ken Lay wrote in a statement posted online.
"We want to assure everyone that we have been paying close attention to this issue and appreciate that so many community members have expressed concern."
