I traveled almost 5 continents in last 30 years and I found Black Magics are common practices in most countries. Particularly among the Muslims from Islamic or non Islamic countries. I don't want to discuss how to remove black magic or how to cure it or its related because every religion have the remedy to clean dirts of the Black Magic.
I would like to remind world Muslims that the Black Magic in the religion of Islam not only Strictly Forbidden but severe punishments in this world and Hereafter as the story of Prophet Moses & Pharoah, The magicians after defeated they said they believe on Moses and his God! After that this surah mentioned in Holy Quran. Surah Taha.20.74-76.
"Surely, he who comes to his Lord as a criminal (Magics) at Judgement for him is Hell. In there he will neither die nor live, But those who come to Him as believers who have worked righteous deeds- For them are supreme ranks in Garden of Eternity. under which flow rivers, They will live in there forever. Like this is the reward for those who purify themselves of evil!" AuthorWGA-Amazon-New Jersey
