【Watch Young Wife Bai Jie】

The Watch Young Wife Bai JieWomen's Marches that took place all over the world Saturday were about solidarity and activism against the Trump presidency, but they were also a ripe moment for others to come and crash the party.

In Sydney, Australia, for example, an unknown group paid to have "Trump" written in the skies, coinciding with demonstrations through the city centre around 12 p.m.

The company, Skywriting Australia, told The Guardianit was paid A$4,000 for the job. It said the group were Australian Trump supporters who have so far chosen to remain anonymous.

Of course, there were people who didn't appreciate the gesture on social media.

Between 8,000 to 10,000 people attended the march in Sydney, according to organisers. The march was one of 160 cities in 60 countries to hold a demonstration, ranging from Washington D.C. to Antarctica.
