Is my not informing about the websites of usurious banks, while knowing of them, considered a lie and cooperation in sin and aggression?

It is forbidden to deal with usurious banks, whether through borrowing or depositing in a savings account. Similarly, depositing in a current account is prohibited unless it is for the necessity of safeguarding money when an Islamic bank is unavailable. It is also forbidden to engage in other usurious transactions with them. However, it is permissible to deal with them in permissible matters such as transferring money, exchanging currencies, and cashing checks. If you are asked about a usurious bank for a permissible matter, your guidance to it should not be considered as cooperating in sin. If you desire safety, you can use equivocation in your answer without outright lying.
