Here’s a non-paywalled link to an article published in the Washington Post a few days ago. It’s great to see this kind of thing getting some mainstream attention. Young children have not made an informed decision about whether they want their photos posted online.
I share my photos with friends and family using a normal webhost.
I used to upload my artsy photos to DeviantArt, but a year ago I had enough with how slow it had become, so I set up my own small lightweight website using a simple HTML/CSS menu and galleries generated by digiKam that also uses very light jacascript for navigation.
It is blazingly fast and private enough for me.
Until its used to train AI
Not to mention it is probably getting archived by the internet archive (no hate for the internet archive I think its a great idea)
I believe google does respect robots.txt, as for other services I don’t know.
