What should a questioner do after subscribing to a website using a fake visa and creating several accounts?

If a website requires a paid subscription, it is not permissible to create a fake visa to access it, because this constitutes usurping rights and consuming wealth unjustly, as Allah Almighty says: ﴿O you who have believed, do not consume one another's wealth unjustly but only [in lawful] business by mutual consent.﴾.

Whoever has done this must repent to Allah and seek absolution from the website owners by paying the subscription fee or whatever they request, provided it does not exceed its value. If the website is forbidden, there is no obligation to pay money to it; rather, the money should be given as charity, because if the website were to seize this money, it would be obliged to dispose of it. This is what Sheikh Al-Islam Ibn Taymiyyah chose.
