Is designing a website that indexes Arabic websites—and does not contain links to songs or chats, nor accepts advertisements for them—considered a sin that necessitates its removal?

The website is good and provides links to useful Islamic websites, and "whoever guides to good will have a reward like that of its doer." However, it also links to news websites and newspapers that do not adhere to Sharia, and even fight against it. Someone might access these sites through your website and be exposed to evil. Therefore, it is advised to scrutinize the website and limit the links to only Islamic and beneficial websites that do not contradict Sharia; that is safer in this world and the hereafter.
