What is the ruling on entering Facebook pages and YouTube channels that feature horoscopes ("Your Luck Today") to refute them by stating that this is polytheism (shirk) and superstition?

It is forbidden to consult, question, or believe soothsayers. Whoever questions them, their prayers will not be accepted for forty nights, and whoever believes them has disbelieved in what was revealed to Muhammad, peace and blessings be upon him. This includes astrology and horoscopes. As for one who approaches them to denounce them and clarify the ruling of the Sharia, this is permissible, and may even be obligatory, to invalidate their statements. However, if one believes that their denouncement will not achieve the desired outcome, then they should save their time by avoiding such places.
