Some of them were harassed for sure. It's not like that it's not happening every day, everywhere. It's our reality. However, we can't be sure who among them were harassed and who made up a story for some odd reasons. We just can't know that and motives to lie could be various. People are weird. A personal revenge for something else, jealousy, thirst for attention, victim mentality and so on and so on. We should be careful with this because there is always a possibility of ruining someone's career and even life because of fake accusations.
Individuals who habitually indulge in self-victimization (also known as playing the victim) do so for various reasons: to control or influence other people’s thoughts, feelings, and actions; to justify their abuse of others; to seek attention; or, as a way of coping with situations.
