What software you are using ??
... Photo Editor Pro has no "content filter" ...

I am sorry. I should have explained this a little. I was posting on ipernity Android app, and then forgot because of were busy.

I am talking about this old Ipernity S.A. project:

Introducing the new content rating/filtering system (2010) www.ipernity.com/blog/team/243059

Stefan (Kiezkickerde) also wrote about it in 2014:

Content filtering / rating seems to be close to be released www.ipernity.com/blog/kiezkicker/659825

It is much similar than what is use at YouPic. The user is asked to filter their contents already while uploading. Then the audience can equally choose to filter what they wish to see.

And this filter is about filtering what is family friendly and what is not.

I have strict content filtering switched on in my account settings and can see this photo on both desktop browser and Android app. Have you set the photo to a restricted rating? If yes, it seems that filtering doesn't work.

Yes, I had set it for moderate filtering when uploading. I will test some more soon.
