But the thumbnails of games tagged as NSFW is shown By-default from the tags page. A better solution would be to blur them, or better yet don’t show NSFW tags unless the user opts-in to show NSFW content
Viewing post in NSFW Content is shown by default in guest mode
I think there are requirements to not show any adult content in thumbnails though, so why would that matter? I strongly dislike opt-in because it limits visibility to the adult audience as well, many of which do not log in when incognito, etc. Thumbnails are the advertisement, blurring them is making a judgment call on what content should be advertised. The age gate when you click should be plenty.
