What is the duty of Muslims towards those who practice indecency, group sex, زوج swapping, adultery, and sodomy, and is it permissible to visit them, pledge allegiance to them, or interact with them except out of necessity?

Such actions indicate pimping, obscenity, violation of sacred limits, and wrath from Allah. It is feared that those who commit them may be afflicted with a torment similar to that of the people of Lot. They must be denounced, for "whoever among you sees an evil, let him change it with his hand; if he is unable, then with his tongue; if he is unable, then with his heart." The authorities should be informed to deter them, and they should be ostracized, meaning no dealings with them in buying, selling, or visiting, if they persist in their actions.
