Does a Muslim bear the sin of an increase in the number of viewers of a pornographic film or clip that he watched, and if he repents, will Allah forgive him such that the sin of those who watch it thereafter will not be written against him?

"Watching indecencies is forbidden, and if a person causes others to watch them, frequently increasing the number of viewers, then he shares in their sin. And whoever participated in a sin whose effect remains, then regretted it and repented, he must strive to remove the traces of his sins to the best of his ability. Part of this person's repentance is to mitigate the effect of his sin by writing a comment commanding people to fear Allah and forbidding them from looking at this evil."
