Is it permissible to remain in a group that sends pornographic content, deleting this content immediately upon receipt, in order to benefit from the other religious and cultural content sent by the group?

Mailing lists include a mixture of people, and the subscriber makes his email a target for receiving waste and afflictions that corrupt his religion and his Hereafter. There are those who exploit them in spreading indecency and viruses. Although there are those who exploit them in calling to God, the harms resulting from subscribing to them are greater than the benefits, for warding off harm takes precedence over acquiring benefits. It is advisable to unsubscribe from these groups, and one can obtain da'wah messages and شرعية ( Shar'i) benefits by subscribing to the mailing lists offered by trusted Islamic websites.
