Does paying $10 on an online advertising and earning website to activate an account and receive profits later, knowing that this is a one-time procedure, count as Maysir (gambling)?

It is permissible to earn profit from browsing advertisements on the internet if the subscription is free, the advertisements are permissible and do not contain anything forbidden, and the payment is known. If the conditions change and activation with a one-time payment is requested, it is permissible to pay the amount to secure the right and continue the work, provided that no further payment is made. Similar activities should be avoided if it is highly likely that money will be requested at a later stage.
