There are countless examples that you can find out there on the internet, but I'll give only two infamously known incidents.

In August, 2023, after female Spanish football ("soccer") team won world cup against UK's national team, Luis Rubiales, the president of the governing body of football in Spain, gave a 1-sec fleeting celebratory kiss to female football player - Jenni Hermoso.

She didn't mind the kiss at the time, as was seen by her reaction 1hr after the "incident" here.

However, due to how powerful feminism has become, and how many notable people reacted to it, Jenni Hermoso re-calibrated the event in her mind, and later perceived it as much worse than how she'd first perceived it initially. A term called "light-switch effect" was coined here to describe such behavior.

A long time ago, when I was first reading posts in manosphere about women regretting their past consensual sexual encounter and #metoo'ing the men (which in this day and age is easy to do for a woman), I thought that was very rare, turns out it's not. Perhaps, due to women's brains being programmed since early childhood with feminist, misandrist #metoo ideology.

Another example, in January, 2023, in a small Tennessee town 5 police officers were fired after it was uncovered they had sex with a female colleague called Maegan Hall.

The reports didn't indicate non-consensual interactions at the time. Just an adult 26 year old woman hooking up with her fellow colleagues.

But after investigation into the police department, and the news broke, she decided to file a lawsuit against the people she hooked up with, alleging she was pressured into doing it.

An excerpt from her complaint/lawsuit (which was written with the help of her lawyer no doubt):

They colluded in using their authority to systematically disarm her resistance and entrap her in degrading and abusive sexual relationships

It was quite beneficial for Jenni Hermoso to turn around and say she was SA'd by Luis Rubiales. Which is what she did when she filed a lawsuit against him. The benefit includes the connections and stronger support for her in life/society, career opportunities as well as financial ones, she'd be invited to speak at venues and would be heralded as one of the champions of feminism etc.

For Maegan Hall, it's to salvage her reputation, if she did what she did out of her free will - then she's a promiscuous woman, if not, then she's a poor victim ("survivor") who deserves sympathy and whatever perks that come with victimhood status these days.

Guys these days need to ensure that a woman doesn't regret what happened post fact, if doing so becomes beneficial to the woman, otherwise they'll get #metoo'ed and their lives will be ruined forever.
