Ludosky claims legitimacy as a leader of the yellow vest movement because of the 1.19 million people who signed her petition.

In May 2016, after working in international finance at BNP Paribas for eleven years, Ludosky created Fall in Cos', an online organic cosmetics and aromatherapy company.

[4][5][9][10][14] Beyond the goals of the yellow vest movement, Ludosky is an environmentalist, supporting such issues as ending the sale of petroleum using vehicles in France.

[15] Seeking to gain more support for the grievances listed in the petition and rising fuel prices, Éric Drouet reached out to Ludosky in October 2018.

[5] On 27 November the pair met for the first time at the Ministry for the Ecological and Solidary Transition to share their message from Ludosky's petition with the government.

It also saw another yellow vest activist, Maxime Nicolle, question the timing of the 2018 Strasbourg attack and imply it was a false flag.

[4][16] Her goal in these trips was to draw media attention to the fact that the issues raised in the petition impacted more than just the people living in Paris.

[22] During Act XIV around 16 February 2019, Ludosky gave an interview in which she said that yellow vest Saturday protests must not stop, even as participation numbers have been declining weekly.

For example, we need to put more pressure on large companies that do not pay enough taxes, which would fund the reduction of VAT on essential goods, one of our demands.

"[23] Ludosky and Étienne Chouard and attended a 2,000 person strong march in Castres during Saturday Act XIV events.

[24] Following Act XIV, in response to anti-semitic acts during Saturday's march in Paris, there was an open letter asking Priscillia Ludosky, Jacline Mouraud, Ingrid Levavasseur, Drouet, Maxime Nicolle and other yellow vest spokespeople "to condemn the aggression committed against Alain Finkielkraut and the anti-Semitic remarks of which he was the victim.

[4] The pair, Ludosky and Drouet, have accused Jacline Mouraud and Benjamin Cauchy of being in the movement in order to hijack it for their own personal and political ambitions.

[26] This his not her stance anymore, as she is the 9th candidate within the Europe Ecologie - Les Verts list for the 2024 European Parliament election.

Fellow yellow vest activist have praised Ludosky as being calm under pressure and an effective communicator of their message.
