In ancient China, a violation of this law would result in the execution of three generations of the offender's clan.
1) First generation - Offender's parents, uncles/aunts + spouses.
2) Second generation - Offender and spouse, siblings + spouses.
3) Third generation - Offender's children and spouses, cousins + spouses.
4) Extended family of the offender's spouse.
For a more severe violation, nine generations of the offender's family would be removed. Thousands of people could be killed in a single purge.
With countries becoming democratic, lèse-majesté has become somewhat obsolete. In term of punishment, the death penalty has been completely aborted. However, several countries like Thailand still fiercely support this law. As recent as 2015, a man was arrested and faced up to 30 years in prison for insulting Thai king's beloved dog over the Internet.
