As @MortenCopenhagen said, if you want some suggestions it would be better to unlock your profile, because this will give us the possibility to:
see how many hidden contributions you have
see if there is some behaviour that is against the policies
Without that kind of information we can just guess what is going wrong. A few examples from your badges Photos
You added 3743 photos in 616 places
It means an average of around 5 photos per location. This is fine, but without seeing the photos it would be difficult to understand if all are following the rules
Reviews
Despite having 1180 reviews, only 49 of them are considered “helpful”. All the others are very short, probably a single word, like “nice”, “beautiful” and so on
Can you better explain this part? When a photo or a review is hidden it’s not visible to the public, but is still visible on your profile.
The only case when a review is not visible on the profile is when the place has been removed from Google Maps.
In that case the review will disappear, and the photos will be associated to an"unknown place".
There is only an extreme case on which reviews and also photos are deleted from the profile: when the content is related to pornography or terrorism. Obviously this is not the case, otherwise your Google account would be completely deleted, and you not will be able to write here.
As you can see, we need some more information to be able to help you with your issues, otherwise we will be able to only give you some generic answers
