If someone checks someone else's profile, they might see all the games in that user's collection if the said user decided to share their collection.
The problem is that it also shows adult games even if they have not agreed to see adult content. Well, just having them listed isn't the main issue. The issue is that a lot of adult games have adult content directly on their thumbnails to gain more viewers.
This can easily affect those who do not wish to be exposed to such content, or are not legally allowed to.
My suggestion is to blur the adult games' thumbnails if the viewer has yet to agree to see the adult content.
