Is a person sinful if they are a moderator on a website that contains violations, even if their moderation section is free of them?

It is permissible for a student of knowledge to supervise the "Islamic section" in forums and websites, even if they contain some transgressions, due to the pressing need for fatwas and guidance among their visitors, and to prevent supervision by people of innovation and misguidance. However, this is subject to conditions: that the website is not utterly corrupt, that supervision is not understood as an endorsement of reprehensible acts, and that the supervisor is able to write the truth without distortion.
