I bought/redeemed my points for a Premium/VIP membership, but I can't see any NSFW content.

If you've purchased or redeemed points for a Premium or VIP membership, you'll still need to prove your age by taking the 18+ check.

If you're unable to view any NSFW content after taking the 18+ check and being verified, try logging out and then in again or adjust your search settings to include NSFW content.  If the problem persists, submit a ticket to the Support Team, who'll be happy to help.
