Is seizing the login information (passwords) for email accounts of participants in a group that publishes sexual content, with the aim of disabling this group and preventing them from participating in this forbidden act, considered theft that necessitates accountability, and is it permissible to continue doing so?

One must differentiate between two situations when it comes to knowing about sexual correspondences between Muslims:

1. Spying (Tajassus): This is forbidden by Islamic law, based on the Almighty's saying: "O you who have believed, avoid much [negative] assumption. Indeed, some assumption is sin. And do not spy." 2. Knowing without spying: There is no blame on you, and you must denounce the wrongdoing (munkar) to the best of your ability, such as advising the owners of these correspondences. If they do not respond, then exert effort to change the wrongdoing, even if it leads to disrupting the email group or changing passwords.

However, it is not permissible to hack someone's email to view its contents without their permission, based on the Almighty's saying: "And do not transgress. Indeed, Allah does not like transgressors," and based on the Prophet's (peace be upon him) saying: "Whoever looks into his brother's letter without his permission, it is as if he is looking into fire."
