What is the way to deal with a person who blackmails with photos and threatens to expose them, and what should I do after my repentance and regret?

A Muslim woman should remain steadfast in righteousness and beware of Satan, who strives to mislead humanity. If a woman is threatened by a man, she should turn to Allah and supplicate with the prayer: "O Allah, we place You against their throats, and we seek refuge in You from their evils." She should also offer advice to the man, remind him of Allah and His punishment, and threaten to report him to someone who can deter him. If a suitor of good character and religious commitment proposes, she should agree to the marriage and not heed the man's threats. If her pictures are exposed, she should use dissimulation by denying any relationship with him or giving him the pictures, intending thereby what occurred after her repentance.
