What is the ruling on subscribing to an advertising platform that requires a security deposit which is refundable after one year of commitment to specific tasks (such as watching YouTube videos, liking them, and subscribing to channels), with the possibility of retrieving the subscription amount at any time upon withdrawal, and is it permissible to continue working with them as an employee after the capital is recovered?

It is not permissible to work in the manner described due to the presence of subscriptions, which are akin to a loan. It is not permissible to combine a loan with any contract of exchange, such as sale or lease, because the Prophet, peace and blessings be upon him, said: "It is not lawful to combine a loan and a sale." The reason for this is that it is a means to usury. Furthermore, the idea of the tenant placing a deposit for the purpose of deducting rent from it — we do not know of any religious basis for it unless it is in the form of a penalty clause. In that case, its estimation must be based on the actual value of the damage incurred by the affected party, and the absence of an excuse for the other party. The act itself — watching YouTube videos, subscribing to channels, and liking them — its ruling varies according to the questioner's situation and the type of videos.
