Is it permissible to participate in an online competition that requires publishing photos about oil and gas, in which 50 contestants win based on accumulating points through uploading photos and liking and commenting on them, knowing that internet usage will be either from work without restrictions or from home via subscription cards designated for public use?

There is no objection to participating in the competition as long as it does not require an entry fee and does not make the participant oscillate between gain and loss, which would then be gambling. It is not permissible to use the internet at the workplace for this purpose except with the permission of the employer. There is no objection to connecting to the internet with prepaid cards, even if bought specifically for this purpose, as long as the cost of the connection is the normal cost and is not increased for the sake of participating in the competition.
