In the Name of Allah, the All-Merciful, the Mercy-Giving

 

All praise is due to Allah. Peace and blessings be upon His Messenger Muhammad.

 

The Prophet (peace be upon him) said: “All of my Ummah (people) are in well (status) except for those who expose (themselves.)” (Al-Bukhari)

 

We have no right to expose anyone who committed a sin in private at all. If we want to advise them privately that is ok.

 

Although people might not forget sins of people who were public in their sins but yes indeed Allah Almighty can forgive all sins and that is the only thing a person should be worried about of how Allah Almighty looks at him. Allah said: “Say, O My servants who have transgressed against themselves [by sinning], do not despair of the mercy of Allah . Indeed, Allah forgives all sins. Indeed, it is He who is the Forgiving, the Merciful.” (Az-Zumar 39:53)

 

Almighty Allah knows best.
