Since 1990, 62 people have been murdered following blasphemy allegations. According to one religious minority source, an accusation of blasphemy commonly exposes the accused, police, lawyers, and judges to harassment, threats, attacks and rioting. Critics complain that Pakistan's blasphemy laws are "overwhelmingly being used to persecute religious minorities and settle personal vendettas," but calls for change in blasphemy laws have been strongly resisted by Islamic parties - most prominently the Barelvi school of Islam. Many atheists in Pakistan have been lynched and imprisoned over unsubstantiated allegations of blasphemy. When the state initiated a full-fledged crackdown on atheism since 2017, it has become worse with secular bloggers being kidnapped and the government running advertisements urging people to identify blasphemers among them and the highest judges declaring such people to be terrorists.
