World naked bike ride

I have always pondered how much female participants of the WNBR are the real protesters and how much are just exhibitionists. What makes young female to strip and come in front of people to ride through city?
Of course I like it, but I still doubt they want to participate because of the purpose of the cleaner world. Very often it looks likes they just came to show themselves. For exhibitionists WNBR is an ideal possibility to come and show up legally and nobody have doubts.
Who look like exhibitionist females?
1) Riders who participate without body-paint and/or barefoot.
2) Riders with shaved pussy
3) Riders who come alone without boyfriend
4) Riders who strip long before start
5) Riders who have attractive body
Of course not all five characteristics does not have to be matched, but at least 3-4 of them.
For example these girls have all signs of the exhibitionists: https://xhamster.com/photos/gallery/14104523/393587474 and https://xhamster.com/photos/gallery/14577629/419227786 and https://xhamster.com/photos/gallery/12068928/287277905
What you think about this topic? Am I right if I say: 60-70% of female WNBR participants are exhibitionists?
