What is the ruling on earning profit from clicking on ads and participating in forums for money?

Receiving payment for clicking on and browsing advertisements is permissible if no fees are stipulated for the subscriber, provided it pertains to permissible advertisements, and does not involve deception or trickery towards the advertising party. As for participating in forums and receiving payment for it, there is no harm in it if it is free from শরী'আ-prohibited elements, such as forums that do not promote vice and moral decay.
