Is it permissible to pay a sum of money to a number of individuals in exchange for them registering on a halal website, knowing the amount of profit from each person's registration?

There is no objection to the aforementioned work if registration on the site is free, and your work is permissible, such as browsing, subscribing, or honest surveying, and the commission is known. It is forbidden to deal with the site if it defrauds investors or advertisers, or if its content is impermissible, or if you defraud it by creating multiple accounts.
