Is it permissible to advertise permissible products, such as computers or phones, on pornographic websites?

Selling permissible goods to visitors of malicious websites is permissible, like other sales. However, the problem lies in condoning and dealing with these websites, which contradicts the obligation to abhor them, denounce them, and strive for their closure. The duty is to deal with them in accordance with the verses of the Holy Quran and the sayings of the Prophet (peace be upon him) which command the prohibition of corruption and the changing of evil. Can acting upon these texts be reconciled with advertising on these websites? The situation of one who does so resembles that of the People of the Sabbath, whose action outwardly appeared permissible but inwardly was a transgression.
