The anonymity of the internet and Reddit in particular ironically allows people to share things with millions that they could never conceive of telling a single person face to face. Reddit is often able to get spectacular confessions out of people for this reason, and that is showcased in this collection of 22 people sharing their deepest darkest secrets on Ask Reddit. 

Two people here told of inter-family affairs, but don't worry, not the actual relative kind. "My stepdad's brother's stepdaughter," one man admits. "Same age, and every time we meet up for family gatherings it happens. I've lost track of how many times. We are both in our 40s and have never actually spoken about it." But while that guy seems to have a decent system set up for himself, another man who had a thing with his "Mom's half-sister's brother-in-law's daughter" admitted that his family started to wise up. "My Mom started to get suspicious so we stopped." Maybe he should keep his secrets better. 

As for keeping secrets, one man here admits to covering for his great-grandfather's violent acts with a baseball bat in the bar he owned in Brazil. "Shh, don't tell anyone," the great-grandfather told him. Reddit in 2024 was the first place to know.
