Is it permissible to advertise a money transfer feature through non-Islamic banks that require opening an account with them, on a website owned by the person?

It is not permissible to open an account in a usurious bank, nor to transfer money through it, except in cases of extreme necessity, due to the cooperation in sin and aggression involved. Therefore, it is not permissible to advertise for a usurious bank, as this entails promoting and encouraging it, and leads to opening accounts and transferring money through it.
