Is the partner absolved who separated from a forum that includes sections violating Sharia, after he asked his other partner to donate his share of the forum to the poor and needy?

Aiding in the spread of evil deeds and the propagation of indecency is a grave sin, and its perpetrator must repent to Allah. The one who repents must strive to remove all traces of his corruption, erase the evil he has spread, and invite people to goodness. The questioner must close the sections of the forum that violate Islamic law, or close the entire forum if he is able. If he is unable, then he must strive to call to goodness, spread virtue, and combat vice.
