Violating Flickr's terms of service
Flickr said I had violated their terms of service by having non-photographic content
Another user had reported this.
I had not been using my Flickr account much so I experimented by adding images with captions containing tips and news. The images were drawings from 'openclipart.org'. I also made a gallery of screenshots of my game.
I removed these images. I left some graphs showing probability distributions of getting a 'line' or 'house' in bingo.
I had no more trouble for a few months.
But now, I cannot login. Flickr says my username is not valid. If I use a link to my images, then I get a a '410' HTTP code meaning the content was intentionally removed.
Yahoo! acquired Flickr in 2005. Yahoo! let you store lots of images, and even videos.
In 2018, Yahoo! (now owned by Verizon) sold Flickr to SmugMug. Now Flickr tries to be a community of photographers.
I still have all the same images on Pinterest together with the captions Pinterest only allows short caption, so I have to truncate my tips
