Should one advise the owner of a website that has become a tool for evil and harassment due to user subscriptions and conversations with girls?

It is not permissible for a man to create or enter websites that lead to the spread of indecency, for their owner falls under the warning of the verse: (Indeed, those who like that indecency should be spread among those who believe will have a painful punishment in this world and the Hereafter). This path leads to the loss of faith and honor, and in some cases, suicide.
