my husband's Instagram is questionable....

Hi I am looking for opinions or answers. I have been logging into and checking out my husbands Instagram page. On the "Explore" tab it is 90% full of pictures and videos of very young gymnasts. He never likes or comments on any posts at all and has no history of likes or comments. I have googled this to find out more about how the Explore page in IG works and it just says its tailored to posts that you like/comment on. Any suggestions why these would be coming up on his page? I have been looking every day for a week, and that's always what is on there. it hasn't changed. I would hate to assume the worst but I think he must be viewing these types of photos and videos in order for them to populate on the page like that.
